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.-Karlee
