Kinetic and Potential Energy Practice

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It is often associated with gravitational energy when an object is elevated.

Front

At which point in a pendulum's swing is potential energy the greatest?

Back

At the highest point of the swing.

Front

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

Back

At the lowest point of the swing.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

When a roller coaster is at the top of a hill, what type of energy is highest?

Back

High potential energy.

Front

When a roller coaster is at the bottom of a hill, what type of energy is highest?

Back

High kinetic energy.

Front

True or False: When an object's kinetic energy increases, its potential energy must decrease.

Back

True.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.
