Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity.

Front

How does mass affect potential energy?

Back

The amount of material (mass) affects the potential energy; more mass means more potential energy when at the same height.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy quadruples.

Front

What happens to kinetic energy when an object slows down?

Back

As an object slows down, its kinetic energy decreases.

Front

Can kinetic energy be converted to potential energy?

Back

Yes, kinetic energy can be converted to potential energy, such as when an object is lifted against gravity.

Front

Where is kinetic energy greatest on a roller coaster?

Back

Kinetic energy is greatest at the bottom of the highest hill on a roller coaster.

Front

Where is potential energy greatest on a roller coaster?

Back

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

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
