Kinetic and Potential Energy Review

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What type of energy does a person climbing a ladder have?

Back

A person climbing a ladder has both potential and kinetic energy.

Front

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of a hill on a roller coaster.

Front

What happens to potential energy as an object falls?

Back

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

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

What is the formula for calculating Potential Energy?

Back

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

Front

Give an example of an object with high potential energy.

Back

A ball resting on the edge of a cliff has high potential energy.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and potential energy can transform into each other; for example, potential energy converts to kinetic energy when an object falls.
