- Physics Unit 1
- Convection
- Happens in liquids and gases
- Particles do NOT expand
- If the particles are more dense, they float down
- If the particles are less dense, they float up
- If the particles are more dense, they float down
- Particles do NOT expand
- Happens in liquids and gases
- Radiation
- Involves only waves
- Black is the best absorber and emitter
- Silver is the worst absorber and emitter
- Makes the light BOUNCE off the surface
- Silver is the worst absorber and emitter
- Black is the best absorber and emitter
- Involves only waves
- Specific Heat Capactiy
- E= M x C x O
- Energy transferred= Mass X SHC x Temp change
- Measured in Joules
- Measure of thermal energy contained in an object
- E= M x C x O
- Energy use in home
- KWh= kw x h
- Example 0.16KW x 24 = 3.84 KWh used in home
- Finding price by using energy used = KWh x Price (in pence or pounds)
- Example- 110KWh x 0.15 = £16.50 9Electricity bill)
- Finding price by using energy used = KWh x Price (in pence or pounds)
- Example 0.16KW x 24 = 3.84 KWh used in home
- KWh= kw x h
- Waves
- Vibrations that transfer energy from place to place without matter.
- Some waves must travel through a substance.(Sound waves, Seismic waves)
- Amplitude- maximum disturbance from its undisturbed position.
- Wavelength- distance between a point on once wave and the same point on the next.
- Amplitude- maximum disturbance from its undisturbed position.
- Frequency- Number of waves produced by a source each second.
- Unit- Hertz (Hz)
- Diffraction- Waves meet a gap- waves spread to some extent into the area beyond gap.
- Wave speed equation- V= F x (lambda) M
- frequency and time period- 1 divided by Time Period- F= 1 divided by T
- Convection
