PE & KE Formative

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 square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical energy.

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

What factors affect Potential Energy?

Back

Potential Energy is affected by the object's mass and its height above the ground.

Front

What is the relationship between Kinetic Energy and Potential Energy?

Back

Kinetic Energy and Potential Energy are forms of mechanical energy. They can be transformed into each other; for example, when an object falls, its Potential Energy converts to Kinetic Energy.

Front

At which point is Potential Energy greatest in a roller coaster?

Back

Potential Energy is greatest at the highest point of the roller coaster.

Front

What is an example of Kinetic Energy?

Back

A moving car, a running athlete, or a flowing river are examples of Kinetic Energy.

Front

What is an example of Potential Energy?

Back

A drawn bow, a book on a shelf, or a compressed spring are examples of Potential Energy.

Front

How does mass affect Kinetic Energy?

Back

Increasing the mass of an object increases its Kinetic Energy if the velocity remains constant.

Front

How does velocity affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the velocity; if the velocity doubles, the Kinetic Energy increases by four times.
