PE & KE Practice

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How can you increase gravitational potential energy without changing mass or gravity?

Back

By raising the object higher off the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

Calculate the kinetic energy of a 3 kg rabbit moving at 0.5 m/s.

Back

0.375 J

Front

What is the formula for calculating gravitational potential energy?

Back

PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy does a moving skateboard have?

Back

Kinetic energy.

Front

Can energy change forms?

Back

Yes, energy can be transformed from one form to another, such as from potential energy to kinetic energy.

Front

What happens to gravitational potential energy when an object is lowered?

Back

The gravitational potential energy decreases as the height of the object decreases.

Front

If an object is at rest, what type of energy does it have?

Back

Potential energy, if it is positioned in a gravitational field.

Front

What is the gravitational potential energy of a 65 kg climber at a height of 8.8 km?

Back

5605 J
