Topic 1: Motion, forces and energy

  • Acceleration = ?v / ?t
  • Average speed = Total distance / Total time
  • Density = Mass / Volume
  • Hooke’s law: F = kx
  • Impulse = Force × Time
  • Kinetic energy = 0.5 m v2
  • Moment = Force × perpendicular distance from pivot
  • Newton’s second law: F = ma
  • Percentage efficiency = [Useful energy output / Total energy input] × 100
  • Percentage efficiency = [Useful power output / Total power input] × 100
  • Potential energy = m g h
  • Power = Energy transferred / Time
  • Power = Work done / Time
  • Pressure = Force / Area
  • Pressure = Height × Density × g
  • Resultant force = ?(momentum) / ?t
  • Speed = Distance / Time
  • Weight = Mass × g
  • Work = Force × distance along force
