Gravitational Potential and Kinetic Energy

Front

What is Gravitational Potential Energy (GPE)?

Back

Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, calculated as GPE = mass x gravity x height.

Front

How is Kinetic Energy (KE) defined?

Back

Kinetic Energy (KE) is the energy an object has due to its motion, calculated as KE = ½(mass) x (velocity)².

Front

What is the formula for calculating Gravitational Potential Energy?

Back

GPE = mass x gravity x height.

How much KE does a 50 kg person running at 7 m/s have?

Back

1225 J.

Front

What happens to KE as mass increases, assuming velocity remains constant?

Back

KE increases.

What is the GPE of a 100 kg bell at the top of a 45 m tower?

Back

44100 J.

Front

What is the effect of height on Gravitational Potential Energy?

Back

As height increases, GPE increases.
