Kinetic and Potential Energy Transformations

Front

What type of energy is stored when you stretch a rubber band?

Back

Potential energy.

Front

What is the energy delivered by tiny charged particles called electrons?

Back

Electrical energy.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

At the lowest point of the swing.

Front

How can we increase the gravitational potential energy of an object?

Back

By increasing its mass or height.

Front

What is stored energy also known as?

Back

Potential energy.

Front

What is the formula for gravitational potential energy?

Back

PE = mgh (where m = mass, g = acceleration due to gravity, h = height).

Front

What happens to potential energy as an object falls?

Back

It is converted to kinetic energy.

Front

What is kinetic energy?

Back

The energy of an object in motion.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; KE = 1/2 mv².

Front

What is the relationship between kinetic and potential energy in a roller coaster?

Back

As the coaster climbs, potential energy increases; as it descends, kinetic energy increases.
