Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height and mass of the object.

Front

When is an object said to have maximum Kinetic Energy?

Back

An object has maximum Kinetic Energy when it is moving at its highest speed.

Front

What happens to energy when a roller coaster goes up a hill?

Back

As a roller coaster goes up a hill, Kinetic Energy is converted into Potential Energy.

Front

What happens to energy when a roller coaster goes down a hill?

Back

As a roller coaster goes down a hill, Potential Energy is converted into Kinetic Energy.

Front

Give an example of Potential Energy.

Back

A baseball held by a pitcher has Potential Energy because it is held at a height.

Front

Give an example of Kinetic Energy.

Back

A moving car has Kinetic Energy because it is in motion.

Front

What is the formula for 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 Gravitational Potential Energy?

Back

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