Gravitational Potential Energy (GPE)

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, typically calculated as GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy is stored energy?

Back

Potential energy.

Front

How can you increase the potential energy of an object without changing its mass and gravity?

Back

By raising the object farther off the ground.

Front

At which point does an object have the least gravitational potential energy?

Back

At the lowest point in its position relative to the ground.

Front

What is the formula to calculate Gravitational Potential Energy?

Back

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

Front

If an object has a mass of 10 kg and is 5 m high, what is its GPE?

Back

GPE = 10 kg * 10 m/s² * 5 m = 500 J.

Front

What happens to GPE when an object is dropped from a height?

Back

The GPE decreases as the object falls, converting to kinetic energy.

Front

What is the unit of measurement for energy?

Back

Joule (J).

Front

If the height of an object is doubled, what happens to its GPE?

Back

The GPE also doubles, assuming mass and gravity remain constant.

Front

What is the relationship between height and gravitational potential energy?

Back

Gravitational potential energy is directly proportional to height.
