KE & GPE

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 Gravitational Potential Energy?

Back

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

Front

How can you increase Gravitational Potential Energy without changing mass or gravity?

Back

You can increase Gravitational Potential Energy by raising the object farther off the ground.

Front

Which has greater Gravitational Potential Energy: a 4lb rat on a desk or a 45lb dog in a tree?

Back

A 45lb dog in an oak tree has greater Gravitational Potential Energy due to its greater weight and height.

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 (GPE) is GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is Energy?

Back

Energy is the ability to cause change or do work.

Front

What type of energy is associated with an object at rest?

Back

Potential Energy is associated with an object at rest.

Front

What type of energy is associated with an object in motion?

Back

Kinetic Energy is associated with an object in motion.

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.
