Kinetic and potentional energy
Kinetic Energy
Definition:
Kinetic energy is the energy of a moving object.
Examples:
A rolling ball
A moving car
Flowing water
A flying bird
Key idea:
If it is moving, it has kinetic energy.
Potential Energy
Definition:
Potential energy is stored energy.
Examples:
A book kept on a shelf
A stretched rubber band
Water stored in a dam
A compressed spring
Key idea:
If energy is stored, it is potential energy.
Simple difference:
Kinetic = moving
Potential = stored
Fun Fact:
When a car doubles its speed, its kinetic energy (energy of motion) doesn't just double, it quadruples (becomes four times greater), making high-speed crashes much more devastating than low-speed ones,
