- Equations
- Wave Properties and Sound
- wave speed = frequency x wavelength
- v=f?

- frequency = 1 / time
- f=1/t

- wave speed = frequency x wavelength
- Describing Motion
- average speed = distance travelled / time taken
- s=d/t

- acceleration = change in velocity / time taken
- a=(v-u)/t

- average speed = distance travelled / time taken
- Behaviour and Uses of Light
- refractive index of substance = speed of light in air / speed of light in substance
- refractive index = sine of angle of incidence / sine of angle of refraction
- n=sin i/sin r

- sine of critical angle = 1 / refractive index
- sin c=1/n

- How Forces Affect Motion
- force = mass x acceleration
- f=ma

- weight = mass x gravitational field strength
- w=mg

- force = mass x acceleration
- Simple Electric Circuits
- charge = current x time
- q=it

- energy transferred = potential difference x charge
- e=vq

- resistance = potential difference / current
- r=v/i

- charge = current x time
