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.

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 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.

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
