Study Notes
Gravitational Potential Energy
- Gravitational potential energy is defined as the energy an object possesses due to its position or configuration within a gravitational field.
- It is the potential energy associated with the gravitational force between an object and a massive body such as the Earth.
Role of Distance
- Distance plays a crucial role in gravitational potential energy as it affects the strength of the gravitational force between objects.
- As the distance between objects increases, the gravitational force and thus the gravitational potential energy decrease.
Concept of Infinity
- In the context of gravitational potential energy, 'infinity' refers to a hypothetical point where the object is at an infinite distance from the massive body, such as the Earth.
- At this point, the gravitational potential energy is considered to be zero, as the gravitational force is negligible at infinite distances.
