Kinetic and Potential Energy Review

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 can be gravitational (due to height) or elastic (due to deformation).

Front

What factors affect Potential Energy?

Back

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

Front

What is the formula for calculating 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 calculating 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.

Front

How does mass affect Kinetic Energy?

Back

The greater the mass of an object, the greater its Kinetic Energy if the speed remains constant.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the greater its Potential Energy, assuming mass remains constant.

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 relationship between Kinetic and Potential Energy in a roller coaster?

Back

In a roller coaster, as the car goes up, Potential Energy increases and Kinetic Energy decreases; as it goes down, Kinetic Energy increases and Potential Energy decreases.

Front

What is an example of Potential Energy?

Back

A drawn bow has Potential Energy due to the tension in the string and the position of the arrow.
