Study Notes
Energy Basics
- An object at rest at a height, such as a ball at the top of a hill, is an example of potential energy.
Law of Conservation of Energy
- The law of conservation of energy states that the total energy of an isolated system remains constant over time, but can be converted from one form to another.
Gravitational Potential Energy
- The mass of an object and its height above the ground are the two factors that affect its gravitational potential energy.
- The gravitational potential energy of an object does not depend on its shape or color.
