Forms of Energy and Cheetah Speed Quiz

Energy is the capacity to cause change and the ability to rearrange a collection of matter.

The different forms of energy mentioned are kinetic, light, and potential energy.

Living organisms are open systems because energy and matter can be transferred between the system and its surroundings.
