Back
Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, calculated using the formula GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

FLASHCARD QUESTION
Front
What is the formula for calculating Gravitational Potential Energy?
Back
The formula for calculating Gravitational Potential Energy (GPE) is GPE = mgh, where m is the mass of the object in kilograms, g is the acceleration due to gravity in m/s², and h is the height in meters.

FLASHCARD QUESTION
Front
How does mass affect Gravitational Potential Energy?
Back
The greater the mass of an object, the greater its Gravitational Potential Energy at a given height, since GPE is directly proportional to mass.

FLASHCARD QUESTION
Front
What is the role of height in determining GPE?
Back
Height is directly proportional to Gravitational Potential Energy; as the height increases, the GPE increases, assuming mass and gravity remain constant.

What is the standard acceleration due to gravity on Earth?
Back
The standard acceleration due to gravity on Earth is approximately 9.8 m/s².

FLASHCARD QUESTION
Front
If a 64 kg person is at an elevation of 5334 m, what is their GPE?
Back
GPE = mgh = 64 kg * 9.8 m/s² * 5334 m = 3,345,484.8 J.
7.
FLASHCARD QUESTION
Front
How do you find the height if you know the GPE and mass?
Back
Rearrange the GPE formula: h = GPE / (mg). For example, if GPE = 1970 J and m = 82 kg, then h = 1970 J / (82 kg * 9.8 m/s²) = 2.5 m.
