Gravitational Potential Energy

Front

What does gravitational potential energy depend on?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

What is the correct unit for expressing gravitational potential energy?

Back

Joule

Front

Calculate the gravitational potential energy (GPE) of a 1 kilogram book that is 1 meter above the ground (g = 9.8 m/s²).

Back

9.8 Joules

Front

What is the definition of energy?

Back

Energy is the ability to do work.

Front

Which object has the least gravitational potential energy?

Back

A ball sitting on the ground.

Front

What is the formula for calculating gravitational potential energy?

Back

GPE = mass × gravity × height.

Front

What is the value of gravitational acceleration (g) on Earth?

Back

Approximately 9.8 m/s².

Front

If an object is lifted higher, what happens to its gravitational potential energy?

Back

Its gravitational potential energy increases.

Front

What happens to gravitational potential energy if the mass of the object is doubled?

Back

The gravitational potential energy also doubles.

Front

What is the gravitational potential energy of a 2 kg object at a height of 5 meters? (g = 9.8 m/s²)

Back

GPE = 2 kg × 9.8 m/s² × 5 m = 98 Joules.
