Study Notes
Energy Types
- Kinetic Energy has several types: Sound, Heat, Electrical, Mechanical, Radiant, and Light
- Potential Energy has several types: Chemical, Elastic, Gravitational, Nuclear, and Magnetic
Energy Measurement and Principles
- Energy is measured in joules
- Energy can be transformed, meaning it changes from one form to another
- Energy can be transferred, meaning it is passed from one object to another
- The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed
Energy Efficiency and Output
- Useful energy is the desired output energy
- Wasted energy is the unwanted or undesired output energy
- Energy efficiency is the measure of how much input energy is converted into useful output energy
- Example: electric toothbrush - input energy is electrical, output energy is kinetic, wasted energy is heat and sound
Energy in Action
- Energy makes things happen and is observed
- Work is being done when a force moves an object, causing it to move a certain distance
