Physics
- Energy
- Nine types of energy
- Heat
- Heat Transfer
- Conduction
- Vibrating particles pass on the heat energy
- Convection
- Substance becomes less dense as heated particles move
- Radiation
- Heat is transferred in waves
- LIght
- Sound
- Nuclear
- Gravitational Potential
- Electric
- Chemical Potential
- Elastic Potential
- The Law of Conservation of Energy
- Energy cannot be created or destroyed only transferred from one form to another.
- Equations
- Efficiency
- Useful Energy / Total Energy In
- Weight
- Mass X Gravitational Constant (10)
- Work Done
- Force X Distance
- Power
- Work Done / Time taken
- Solids, Liquids and Gases
- Equations
- Density
- Mass / Volume
- Pressure
- Force / Area
- Pressure Difference
- h X p x g
- h= height difference
- p= density
- g= gravitational constant (10)
- Solid to a liquid is melting
- Liquid to a solid is freezing
- Liquid to a gas is evaporation
- Brownian motion is evidence of gas particles moving
- Gas to a liquid is condensing
- 0K = -273 C
- Waves
- The Electromagnetic Spectrum
- Radio Waves
- Microwaves
- Infrared Radiation
- Visible Light
- Ultra Violet Light
- Gamma Rays
- X- Rays
- Equations
- Period
- 1 / Frequency
- Speed
- Frequency X Wavelength
- Reflection
- Angle of Incidence = Angle of Reflection
- Refraction
- Light Changes Medium
- Going in angle of incidence bends towards norml
- Opposite going out
