Study Notes
Gravitational Potential Energy and Height
- Gravitational potential energy is the energy an object has due to its height or position in a gravitational field.
- The higher an object is, the more gravitational potential energy it has.
- As an object gains height, its gravitational potential energy increases.
Factors Affecting Gravitational Potential Energy
- Height (h): The primary factor affecting gravitational potential energy is the height of the object above the ground or a reference point.
- Mass (m): The mass of the object also affects its gravitational potential energy, but height is the more significant factor.
Elevation and Gravitational Potential Energy
- Elevation: Elevation is the height of an object above a specific reference point, such as sea level.
- An object's gravitational potential energy increases as its elevation increases.
- The relationship between elevation and gravitational potential energy is directly proportional: as elevation increases, gravitational potential energy also increases.
Key Formula
- The formula for gravitational potential energy is: U = mgh
- U = gravitational potential energy
- m = mass of the object
- g = acceleration due to gravity (approximately 9.8 m/s² on Earth)
- h = height or elevation of the object
