Unit 4 Force and Energu

Front

What is Potential Energy?

Back

Stored Energy

Front

What is Accelerating?

Back

How fast an object speeds or slows down

Front

Which bowling ball has LESS kinetic energy? (8 m/s, 10 m/s, they have the same amount of energy, none of these)

Back

8 m/s

Front

What is Friction?

Back

Stops or slows down an object

Front

A dog that is accelerating is... (Standing still, Maintaining its speed, Decreasing in weight, Slowing Down)

Back

Slowing Down

Front

What is Kinetic Energy?

Back

Energy in motion

Front

What happens to potential energy when an object falls?

Back

It converts to kinetic energy

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What is the effect of friction on motion?

Back

It opposes motion and can slow down or stop an object

Front

What is the relationship between mass and kinetic energy?

Back

More mass means more kinetic energy if speed is constant
