Physics- kinetic energy

• Kinetic Energy


  The energy a mass has because it is moving
• Unit for energy


  joule (J)
• Unit for mass


  kilogram (kg)
• Rearrange Kinetic Energy equation to make mass the subject

  m=2Ek/v²
• Rearrange Kinetic Energy equation to make velocity the subject


  v=√(2Ek/m)
• Write the unit used for speed


  M/s
• Write the equation used to calculate kinetic energy

  Ek = 1/2mv squared
