Study Notes
Energy
- Energy is the ability to do work or cause change.
- Many forms of energy exist, including kinetic, potential, thermal, light, and chemical energy.
- Energy cannot be created or destroyed; it only changes forms (law of conservation of energy).
Force and Energy
-
Forces and Motion:
- Force is a push or pull that can change an object's motion.
- Forces can transfer energy (e.g., kicking a ball).
-
Work and Energy:
- Work is done when a force moves an object over a distance.
- Work transfers energy between objects.
-
Kinetic and Potential Energy:
- Kinetic energy increases with increasing speed.
- Potential energy increases with height or stretching.
-
Energy Transfer:
- Energy moves between objects or changes forms.
-
Power:
- Power is the rate at which energy is used or work is done. Higher power means faster energy use.
