Study Notes
Energy Defined
- Energy is the ability to do work or cause change.
- Energy is needed for all processes like movement, heating, or light production.
- There are many forms of energy.
Types of Energy
- Kinetic energy: Energy of moving objects
- Potential energy: Stored energy (e.g., water in a dam, stretched rubber band)
- Thermal energy: Heat energy
- Light energy: From the sun or a light bulb
- Chemical energy: Stored in food or fuel
Law of Conservation of Energy
- Energy cannot be created or destroyed.
- It only changes from one form to another.
Understanding Force and Energy
Forces and Motion
- A force is a push or a pull that causes movement, stopping, or direction changes.
- Forces can transfer energy (e.g., kicking a ball).
Work and Energy
- Work is done when a force moves an object over a distance (e.g., lifting a box).
- Work transfers energy between objects.
Kinetic and Potential Energy
- Kinetic energy increases as an object moves faster.
- Potential energy increases with increased height or stretching.
Energy Transfer
- Energy moves between objects or changes forms (e.g., chemical energy to kinetic energy during running).
Power
- Power is the rate of energy use or work done.
- Higher power objects use energy faster for quicker work.
