Equations

• average speed


  distance moved / time taken
• acceleration


  change in velocity / time taken
• Calculating final speed^2


  (final speed)2 = (initial speed)2 + (2 × acceleration × distance moved)
• force


  mass × acceleration
• weight


  mass × gravitational field strength
• power


  current × voltage
• energy transferred


  current × voltage × time
• voltage


  current × resistance
• charge


  current × time
• energy transferred


  charge × voltage
• wave speed


  frequency × wavelength
• frequency


  1 / time period

  work done = force × distance moved W = F × d

  gravitational potential energy = mass × gravitational field strength × height

  GPE = m × g × h

  kinetic energy = 1/2 x mass × speed2
• work done = Force x Distance
• gravitational potential energy = mass × gravitational field strength × height
• kinetic energy = 1/2 x mass × speed^2
• power = work done/time taken
