- Physics equations
- Weight = Mass x gravitational field strength
- w=mg

- Force applied to a spring = spring constant x extension
- F=ke

- Acceleration = change in velocity/time taken
- A=#v/t

- Momentum = Mass x Velocity
- p=mv

- Gravitational potential energy = Mass x gravitational field strength x height
- Ep = mgh

- Power = work done/time
- P=W/t

- Energy transferred = Power x time
- E= Pt

- Density = Mass/volume
- P=m/v

- Work done = Force x distance (alone action of force)
- W=Fs

- Distance Travelled = Speed x Time
- s=vt

- Kinetic energy = 0.5 x mass x speed^2
- Ek= 0.5mv^2

- Power = energy transferred/ time
- P=E/T

- Moment of a force = Force x distance
- M=Fd

- Wave speed = Frequency x wavelength
- V=fh

- Potential difference = Current x resistance
- V=IR

- Power= current^2 x resistance
- P=I^2R

- Energy Transferred = Charge Flow x Potential difference
- W=QV

- Pressure = force normal to surface/ are of surface
- P=F/A

- Weight = Mass x gravitational field strength
