Definition:

Kinetic energy is the energy of movement.Anything that is moving — even a tiny ant — has kinetic energy.

Main Points:

• If something moves, it has kinetic energy.

• The faster it moves, the more kinetic energy it gets.

• Heavier things have more kinetic energy when they move.

• When something stops, its kinetic energy becomes 0.

• Kinetic energy can change into other energies (like sound or heat).

Interesting Points:

• A tiny pebble rolling fast can have more kinetic energy than a big stone moving slowly.

• When a ball hits the ground, some kinetic energy becomes sound (the thud) and heat (tiny bit).

• Your running body has kinetic energy — that’s why you feel active!

Fun Fact

A cheetah uses LOTS of kinetic energy — it can run faster than a car in traffic!
