Kinetic and Potential energy - Flashcard

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is the energy that 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 speed at which it is moving.

Front

At what point does a roller coaster have the most Potential Energy?

Back

At the highest point of the roller coaster.

Front

At what point does a roller coaster have the most Kinetic Energy?

Back

At the lowest point of the 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 type of energy transformation occurs when a roller coaster descends?

Back

Potential Energy transforms into Kinetic Energy.

Front

When is Kinetic Energy greatest in a pendulum swing?

Back

Kinetic Energy is greatest at the lowest point of the swing.

Front

What is the formula for Kinetic Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

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

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass; if mass doubles, Kinetic Energy also doubles if velocity remains constant.
