Gravitational Potential Energy Flashcard

Front

What is gravitational potential energy?

Back

The energy stored in an object due to its position in a gravitational field.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational Potential Energy (GPE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the value of gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

If a 10 kg mass is lifted to a height of 2 meters, what is its gravitational potential energy?

Back

200 J.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with height.

Front

What happens to gravitational potential energy when an object falls?

Back

It decreases as the object loses height.

A satellite has a mass of 500 kg and is orbiting the Earth at an altitude of 100 km. What is its gravitational potential energy?

Back

5,000,000 J.

Front

At what height is an object that has a mass of 20 kg, if its gravitational potential energy is 7800 J?

Back

39 m.

What is the gravitational potential energy of a roller coaster with a mass of 1000 kg at the top of a 20-meter hill?

Back

200,000 J.

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy is directly proportional to mass.
