Biology / Unit 3 Bio 0489 short lesson, about 20 seconds
Kinetic and Potential Energy
Captions available
The idea
Kinetic energy is the energy of an object in motion; potential energy is the energy an object holds because of its position or structure.
In practice
A wrecking ball swinging has kinetic energy; the same ball held motionless above a car has potential energy instead.
Where people slip
An object at rest is not without energy — its potential energy is not yet released.
