Useful Formulae

  • Speed = distance / time.
  • Force = mass x acceleration.
  • Work = force x displacement in the direction of force.
  • Power = work / time.
  • Ohm law: V = I x R.

Solved Example

Question: A body covers 120 m in 20 s. Find its speed.

Working: Speed = distance / time = 120 / 20.

Result: Speed = 6 m/s.
