Newton’s 1st Law -Meena

Newtons 1st Law is that all objects at rest will stay at rest unless an external force acts upon it.  All objects will continue their original state of uniform and they will always want to return to that state.  This law can commonly be known as inertia. Inertia and the first law is seen everywhere, a demonstration I saw in class was a video of a rock at rest a person came a long and rolled it down a hill making the at rest pebble to become a pebble in motion soon the external force of friction caused the pebble to return to its natural state, at rest.  This video relates to our high five video because a phone lyed on the ground at rest until I came along using my external strength to pick the phone up.  The phone became “apart” of me so as I moved the phone did so we were both in motion.  In the end my video shows clear evidence of Newton’s 1st law because the phone was not going to move unless I, the external force, lifted it up into motion.

*With no outside force this object will never move. With no outside forces this object will never stop.

Gravitational Potential Energy (GPE) -Meena

Gravitational potential energy (GPE) is the level potential energy of gravity acting against a figure.  Everything in the world has gravity acting against it, however the further you are from the earth's core the more GPE you will have. Using that definition my video shows GPE because while I stood on the log I wasn't plummeting to the earth's core it was only when I jumped and became airborne when I began to fall to my next normal force destination.  The examples we saw in class of a boy skating down a hill is GPE because in the simulation we were able to see the level of energy acting on the skater.  I noticed that the further from the ground he was the more GPE.  Knowing this I chose to jump from a log hovering off the ground and fell, as suspected.

Endothermic and Exothermic Heat -Meena

Endothermic heat is when heat is absorbed by a second part such as when you hug someone their body heat is being released and taken in by the other person.  Exothermic heat is when heat is let out.  The sun, for example, is constantly releasing rays of heat therefore it is exothermic.  In my 8th grade science class I did a simulation where there was a fire and water on top.  In this simulation the fire was releasing heat (Exo) and the water was using that heat to boil (Endo).  My video shows endo and exo thermic heat because I sat by a fire that released sparks of flames that warmed me because I was an endothermic example of the fires exothermic exposure. Therefore my Video is endo and exo thermic because it shows evidence of a consumer as well as a producer.

Law of Conservation of Energy -Meena

The definition of the Law of conservation is that energy cannot be destroyed only transferred or transformed.  Transferring energy is when energy moves to one place to another, such as when you plug a charger in an outlet the electrical energy starts in the outlet then moves through the plug to charge your phone.  Transforming energy is when the energy changes its form, for example kinetic energy turning into thermal energy because of friction.  These transfers and transformations occur when forces act upon a subject.  The simulation of a skater rolling until slowly coming to a stop shows the law of conservation because at first the skater was moving so there for it had kinetic energy but it stopped because the friction acting against it built up transforming the energy to thermal.  That simulation relates to the video of me in the water because I was cold I started rubbing my arms and hands so I produced kinetic energy which transformed into heat energy (thermal).   My video is an example of the Law of conservation because energy is neither destroyed nor created but shown as transformed and transferred.

Delayed Gratification -Meena

The Video of me, Meena Felsburg, attempting to eat a candy bar shows delayed gratification.  Delayed Gratification is the ability to resist a temptation that is desired in any way.  An example of delayed gratification is in the beginning of the year when we learned of the experiment conducted on children.  Each child was given one marshmallow if they could wait 5 minutes hey would receive another one.  My video shows this because as I began to put the chocolate in my mouth I was interrupted by Aivy who presented me with a challenge “if you can wait 5 minutes I will give you all of the chocolate.”  I took on this challenge and my dire for more allowed me to wait 5 minute for extra chocolate gratification.  So, because I waited five minutes for a bigger reward my video shows delayed gratification.

How Soap Works? -Ai Vy

We have known that soap is used to wash off oil and grease. It is able to do that thanks to the soap's structure of a non polar tail and a polar head. The tail is non polar and oil is non polar so the tail is able to interact with oil. The head is polar due to unequally distributed electrons, which has the ability to interact with water, which is also polar. Water and oil don't mix because water is polar while oil is non polar, "like dissolves like". Thanks to soap, the oil is formed spherically by the soap structures' tails. Their heads are connected with water so that water and oil are dissolved in a solution. By that, we are able to wash the oil off.  In the video, after Meena ate the chocolate, she went to the bathroom to wash her hands with soap and get rid of the grease on her fingers.

Elements and Compound -Ai Vy

Element is a substance that can not be broken down to any smaller substance of itself. Compound is a combination of two or more elements. In the video, elements and compounds were represented by Snicker bars. Meena hold on Snicker bar and it was an element; Ai Vy hold a few of them together to represent a compound. In chemistry, for example, we have Hydrogen(H) and Oxygen(O) as elements. If we have H2O, a combination of 2 Hydrogens and one Oxygen, we have a water compound.

Power and Energy -Ai Vy

Energy is the ability of a system to do work. The more food we eat, the more energy we absorb, three pieces of candy have more energy than one piece. Power, in the other hand, is how quick or fast energy is being released over time. In the video, after Meena ate a bar of Snickers, she has a lot of energy and she has to dance crazily to burn off those energy. In term of power, after a short time, it is slowly being released.

Newton's Third Law -Ai Vy

Newton's third law states that "Every action has an opposite and equal reaction". This means that there is always a pair of force acting on both interacting objects. In the video, as Karlee hits the ball, she uses a force upon the ball and makes it move. However, according to Newton's third law, the ball also reacts on Karlee racket's with the same amount of force. Thanks to the tennis racket vibration dampener, which role is to reduce or eliminate the vibration coming from the reaction of the ball so that we don't have much impact from that reaction. Another example from our world is when a person punches the wall. The stronger he punches, the more strength the ball will reaction on his knuckles and fist. As a result, it cause injuries.

Acceleration -Ai Vy

Acceleration is change in velocity over time, referring to when we speed up or move at a faster and faster rate. In the video, Karlee runs from the left to right, at first at a pretty fast pace, but slows down over time. In the other hand, Meena runs from the left to the right, slowly at first and after they high five, Meena speeds up. Meena shows how a runner accelerates. In addition, we can see a lot more examples in our real life. For example, when a car turns from a normal street to free way, it speeds up in a significant way. When the velocity of a car becomes faster, it demonstrates acceleration.

Role of Friction in Our World -Ai Vy

Friction is the resistance when the two surfaces come in contact. Friction plays a significant role in our world. Friction appears in daily situations in both a good and bad way. We are able to walk, run or drive our cars thanks to friction. Vehicles don't stop without friction. However, friction cause the car's engine to work less efficiently, and that's why oil is there to reduce friction between parts of an engine. In the video, friction is shown by the ball being rolled on the tennis court. The ball rolls for a while until it is stopped by friction, or in other words, friction slows it down and by that we don’t have to go too far to get the ball back.

Force Diagrams: Thrust and Drag - Frisbee -Karlee

Thrust is what propels and pushes an object forward. An example of thrust is an engine, it pushes an object forward. Drag is the opposite, pushing the object in the opposite direction of motion. Drag could be thought of friction. For example, when you are in a car and you stick your head out of the window you'll feel the drag that the care is creating. The two forces work against each other, but they overcome each other which changes the motion of the object. For example, in our video we featured a Frisbee, when throw into the air, there is thrust that pushes to Frisbee forward, but there is also drag that pushes the Frisbee in the opposite direction, making it slow down and eventually stop. Thrust and drag are essential to how things move, working in opposite ways, they help each determine an object’s motion.

Newton's Second Law - Hitting Tennis Balls Against the Fence -Karlee

Newton’s second law is based on the equation f=ma, where f is the force, m is the mass, and a is the acceleration. This means that force is equal to the product of mass and acceleration. Since changing the mass isn’t possible, changing the acceleration is the key force. The smaller the mass, the more it is allowed to accelerate quickly, and the larger the mass the smaller the acceleration. For example, if you have a motorcycle racing a plane, the motorcycle will accelerate at a faster rate than the plane, giving a big head start, however, once it has been a while the plane will have sped up and have more velocity than the motorcycle because of the build up to its terminal velocity. When we were hitting the tennis ball against the fence, using the racket to do so, made it speed up. The tennis ball’s mass didn’t change throughout the energy transfers. Since the ball had so much acceleration, it hit the fence and sprung back. Meaning that force is measured by both mass and acceleration, as shown with the tennis ball.

Pressure = Force/ Area - Wind Turbine Blades -Karlee

Pressure = Force/ Area. If the force remains the same, the area will determine the pressure. The smaller the area, the more pressure. For example, the reason why laying on a bed of nails is safer than laying on just one. Since the area of the needles has been spread out evenly the pressure would also be spread out evenly too. If there was only one needle, then all the pressure of your body will be in that one point. This is pretty much the reason why bullets are really small. This holds true for wind turbine blades. The big blades didn’t turn as fast because the the pressure of the air blowing on the blades wasn’t as much as the smaller blades. Most of the time that means that the wind turbine with smaller blades produces more energy than those with bigger blades, meaning that the bigger the area, the less the pressure.

Heat Increase Rule - Hitting a Tennis Ball -Karlee

Thermal energy is thought of the most wasteful type of energy out there, it is the ultimate result of every energy will result as heat. You can't do much with heat right now, but as technology advances, solar power would be more common and advanced to create more energy. As potential energy transforms into kinetic energy, which then transforms into heat energy, heat energy will always build up. In other words, the result of energy. It is what is created after the "work" or motion has been completed. In the High Five Video, Karlee and Ai Vy were hitting the tennis ball back and forth proves that because as the ball moves, there were transfers of heat on the court and in the air. This happened until potential and kinetic energy will not exist in the system and its all become into thermal energy.This means thermal energy will always increase in a system, also resulting in the tennis ball stopped.

Kinetic Energy -Karlee

Kinetic Energy is the energy of motion.Something has kinetic energy because it has some kind of motion. Kinetic energy helps us do everything, and is thought as one of the most important energy because we can do so much with it. for example make more different energy with turbines. Whenever something is moving, it has kinetic energy. Kinetic energy comes from potential energy, potential energy to do something, and kinetic energy is that something. Kinetic energy has the ability to do work. Kinetic energy is very powerful because it can overcome many forces, such as gravity. In the video, Ai Vy and Karlee are walking in front of a Church. Walking is a form of kinetic energy because they are in motion.  -Karlee
