Potential and Kinetic Energy Review

Front

What does the conservation of energy principle state?

Back

Energy can be neither created nor destroyed.

Front

True or False: When a tennis ball is dropped, potential energy is destroyed and kinetic energy is created.

Back

False

Front

What type of energy do apples on a tree possess?

Back

Gravitational potential energy.

Front

Which golf ball has greater potential energy if dropped from different heights: a green ball from 7 feet or a yellow ball from 12 feet?

Back

The yellow ball has greater potential energy.

Front

What type of energy is stored in a compressed spring?

Back

Elastic potential energy.

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

How is gravitational potential energy calculated?

Back

Gravitational potential energy = mass × gravity × height.

Front

What happens to potential energy as an object falls?

Back

It is converted into kinetic energy.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed.
