DOL: Kinetic & Potential Energy

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 the speed at which it is moving.

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 the height of an object above the ground.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

How is Potential Energy calculated?

Back

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

Front

What happens to Kinetic Energy as an object speeds up?

Back

As an object speeds up, its Kinetic Energy increases because it is directly proportional to the square of its velocity.

Front

What happens to Potential Energy as an object is lifted higher?

Back

As an object is lifted higher, its Potential Energy increases because it is directly proportional to height.

Front

When is Kinetic Energy at its maximum on a roller coaster?

Back

Kinetic Energy is at its maximum at the bottom of each hill on a roller coaster.

Front

When is Potential Energy at its maximum on a roller coaster?

Back

Potential Energy is at its maximum at the top of each hill on a roller coaster.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has Kinetic Energy.

Front

What type of energy does a book on a shelf have?

Back

A book on a shelf has Potential Energy due to its height above the ground.
