In physics, work is defined as a scalar quantity of an object's change in energy. Energy is directly related to force and displacement. As a result, it is measured in joules, which is the product of Newtons and meters. Like matter and momentum, energy is neither created nor destroyed in an isolated system. However, the energy can transform into other forms. In these blurry pictures, I bounced an exercise ball on the ground. The energy that I lost from bouncing the ball is equal to the energy gained by the ball. As the ball bounces, some of its initial energy turns into heat and sound, so the height of its bounce decreases as time continues.
I love how you used an exercise ball for your example. It was pretty impressive and creative at the same time.
