Equations

• What is the equation for kinetic energy?

  The equation for kinetic energy is 1/2 x mass x velocity^2.
• What is the equation for GPE?

  GPE = mgh (mass x gravity x height)
• What is the equation for power?

  Power = Work / Time

  power = energy transferred/time taken
• What is the equation for efficiency ?

  Efficiency = (Useful output / Total input) x 100%
• What is the equation for charge flow?

  Q = current x time
• What is the equation for potential difference ?

  V = IR
• What is the equation for total resistance ?

  total resistance = resistance of component 1 + resistance of component 2
• What is the equation for power?

  power = IV
