The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
- An object's kinetic energy depends on its mass and its speed.
- The faster something is moving and the heavier it is, the more work it can do.
- Kinetic energy increases as an object moves faster.
- If an objects speed is doubled > kinetic energy is quadrupled.
<em>If an object is not moving, it does not have kinetic energy. </em>
