kinetic energy

• what is kinetic energy?


  the energy stored in moving objects.
• Why don't stationary objects have kinetic energy?


  because they do not move.
• what is the equation for kinetic energy?


  Ek = 0.5 x m x v^2
• what is the unit for kinetic energy?


  Joules (J)
• what is speed measured in?

  m/s
• what is mass measured in?


  kilograms (kg).
• what is 1000J equal to?


  1 kilojoule (kJ)
• what is the reorganised equation for mass?


  m = Ek / 0.5 x v^2
