Gravitational Potential Energy and Kinetic Energy. Elastic

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has due to its motion, which depends on its mass and velocity.

Front

What happens to Gravitational Potential Energy as an object falls?

Back

As an object falls, its Gravitational Potential Energy decreases.

Front

What type of energy does a flowerpot sitting on a windowsill have?

Back

The flowerpot has Potential Energy.

Front

How can you increase an object's Gravitational Potential Energy without changing its height?

Back

You can increase the object's Gravitational Potential Energy by increasing its mass.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

At which length does a spring have the least potential energy when stretched?

Back

The spring has the least potential energy at length A.

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 relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases.

Front

What happens to Kinetic Energy if the velocity of an object doubles?

Back

If the velocity of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.
