Energy store equations

• Kinetic energy store (J) = 1/2 x mass (kg) x speed( velocity(m/s) ) squared

  -> Ek = 1/2 mv2
• Gravitational potential energy store - Change in gravitational potential energy (J) = mass(kg) x gravitational field strength(N/Kg) x height (m)

  -> GPE = MGH
• elastic potential energy (J) = 1/2 x spring constant (N) x extension (m) squared

  -> Ee = 1/2 x k x e2
• Elastic Potential Energy


  A type of potential energy stored in stretched or compressed springs, measured in Joules (J).
• Spring Constant


  A measure of how much force is required to stretch or compress a spring, measured in Newtons per meter (N/m).
• Extension


  The distance a spring is stretched or compressed from its starting position, measured in meters (m).
