Physics 1
- Heat
- Energy= Mass x SHC x Temp Ch
- SLH - Energy into Ch state
- Conduction in solids, vibrations
- Convecton in liquids + gasses,
move from hot to cold
- Radiation, doesn't need materials
- Heat Energy
- Insulation, heat in air pockets
- Thermograms
- Efficiency = useful output / total input
- Sankey Diagrams
- Waves
- amplitude, wavelength, crest, trough
- Speed= Frq x WL
- Diffraction
- refraction - changing direction
- types... R M I V U X G
- Lasers, waves at same freq
- Communication
- Infrared
- Remotes
- Security
- Monitor Temp
- Radio Waves + Microwaves - Long Distance
- Diffraction can effect signal stregnth
- Analogue signals vary,
Digital is On or Off
- Waves and the
Enviroment
- UV (from the sun) causes skin cancer
- The Ozone layer protects us
- (n)SPF sun creams =
(n) x longer in the sun
- Seismic Waves
- P-waves are longditudinal
- P Waves travel in the
direction of the wave
- S-Waves are transvers
- The vibrations travel up
and down
