• What is the formula for distance travelled?

  Distance travelled = average speed × time
• What is the formula for acceleration?


  Acceleration = change in velocity ÷ time taken
• What is the formula for force?


  Force = mass × acceleration
• What is the formula for weight?


  Weight = mass × gravitational field strength

  Change in gravitational potential energy = mass × gravitational field strength × change in vertical height
• What is the formula for kinetic energy?


  Kinetic energy = \(\frac{1}{2} \times \text{mass} \times (\text{speed})^2\)
• What is the formula for efficiency?


  Efficiency = \(\frac{\text{useful energy transferred by the device}}{\text{total energy supplied to the device}}\)
• What is the formula for wave speed?

  Wave speed = frequency × wavelength
• What is another formula for wave speed?

  Wave speed = distance ÷ time
• What is the formula for work done?

  Work done = force × distance moved in the direction of the force
• What is the formula for power?

  Power = work done ÷ time taken
• What is the formula for energy transferred?


  Energy transferred = charge moved × potential difference
• What is the formula for charge?


  Charge = current × time
• What is the formula for potential difference?

  Potential difference = current × resistance

  Electrical power = current × potential difference
• What is another formula for electrical power?


  Electrical power = \((\text{current})^2 × \text{resistance}\)
• What is the formula for density?

  Density = mass ÷ volume
• What is the formula for force exerted on a spring?


  Force exerted on a spring = spring constant × extension
• What is the formula relating final and initial velocity to acceleration and distance?


  \((\text{final velocity})^2 - (\text{initial velocity})^2 = 2 × \text{acceleration} × \text{distance}\)
• What is the formula for force in terms of change in momentum?


  Force = change in momentum ÷ time
• What is the formula for energy transferred in terms of current and potential difference?


  Energy transferred = current × potential difference × time
• What is the formula for force on a conductor in a magnetic field?


  Force on a conductor = magnetic flux density × current × length
• What is the equation for transformers with 100% efficiency?


  Potential difference across primary coil × current in primary coil = potential difference across secondary coil × current in secondary coil
• What is the formula for change in thermal energy?


  Change in thermal energy = mass × specific heat capacity × change in temperature
• What is the formula for thermal energy for a change of state?


  Thermal energy for a change of state = mass × specific latent heat
• What is the formula for energy transferred in stretching a spring?


  Energy transferred in stretching = \(\frac{1}{2} × \text{spring constant} × (\text{extension})^2\)
• What is the formula for moment of a force?


  Moment of a force = force × distance normal to the direction of the force
• What is the formula for pressure?

  Pressure = force normal to surface ÷ area of surface
