Gravitational Potential Energy (GPE)

Front

What is Gravitational Potential Energy (GPE)?

Back

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

Front

What happens to GPE as an object is lifted higher?

Back

As an object is lifted higher, its Gravitational Potential Energy increases because it is further from the center of the Earth.

Front

What is the formula for calculating Gravitational Potential Energy?

Back

The formula for GPE is GPE = mgh, where m is mass (in kg), g is the acceleration due to gravity (approximately 9.81 m/s²), and h is height (in meters).

Front

If a rock weighs 10 kg and is 5 meters above the ground, what is its GPE?

Back

GPE = mgh = 10 kg * 9.81 m/s² * 5 m = 490.5 Joules.

Front

What type of energy does a rock at the edge of a cliff possess?

Back

Potential energy.

Front

At which point does a ball have the least gravitational potential energy?

Back

At the lowest point of its trajectory.

Front

How does the height of an object affect its potential energy?

Back

The higher the object, the greater its potential energy.

Front

What is the relationship between GPE and kinetic energy during free fall?

Back

As an object falls, its GPE decreases while its kinetic energy increases, conserving total mechanical energy.

Front

What is the significance of the reference point in measuring GPE?

Back

The reference point (usually ground level) is crucial as GPE is measured relative to this point.

Front

What happens to GPE when an object is dropped?

Back

When an object is dropped, its GPE is converted into kinetic energy as it falls.
