Potential and Kinetic Energy

Front

What is Kinetic Energy (KE)?

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 (PE)?

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

What factors determine Potential Energy?

Back

Potential Energy is determined by the height (distance) of an object above the ground and its mass.

Front

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 velocity.

Front

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

How does mass affect Kinetic Energy?

Back

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

Front

How does speed affect Kinetic Energy?

Back

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

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases, assuming no energy is lost to friction.

Front

What is the relationship between Kinetic and Potential Energy in a pendulum?

Back

In a pendulum, Kinetic Energy is highest at the lowest point of the swing, while Potential Energy is highest at the highest points of the swing.

Front

What is Work in terms of energy?

Back

Work is done when a force causes an object to move. It is calculated as Work = Force x Distance.
