Potential/ Kinetic Energy Test

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is the energy an object has because of its height above the ground.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is the formula for calculating Potential Energy?

Back

PE = mass x gravitational acceleration (9.81 m/s²) x height.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 x mass x velocity².

Front

What type of energy does a rock at the edge of a cliff have?

Back

Potential Energy.

Front

What type of energy does a moving skateboard have?

Back

Kinetic Energy.

Front

What happens during energy transformations?

Back

Energy changes from one form to another.

Front

How much gravitational potential energy does a 60.0 kg person have at the top of a 74.8 m tall building?

Back

44027.28 J.

Front

How much kinetic energy does a 0.145 kg baseball thrown at 30.0 m/s have?

Back

65.25 J.

Front

What is gravitational potential energy dependent on?

Back

Gravitational potential energy depends on the mass of the object, the height above the ground, and the acceleration due to gravity.
