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 and speed of the object.

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 height and mass.

Front

What factors determine Kinetic Energy?

Back

Kinetic Energy is determined by the mass and speed of an object. The formula is KE = 1/2 mv², where m is mass and v is speed.

Front

What factors determine Potential Energy?

Back

Potential Energy is determined by the height and mass of an object. The formula is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

As the height of an object increases, its Potential Energy increases because it has the potential to fall and do work.

Front

How does mass affect both Kinetic and Potential Energy?

Back

Increasing the mass of an object increases both its Kinetic Energy (if in motion) and its Potential Energy (if elevated).

Front

What is the relationship between Kinetic and Potential Energy?

Back

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

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy is KE = 1/2 mv², where m is mass and v is speed.

What is the formula for calculating Potential Energy?

Back

The formula for Potential Energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy is associated with motion?

Back

Kinetic Energy is the type of energy associated with the motion of an object.
