Kinetic Energy  Kinetic comes from the Greek work ‘to move’  So Kinetic Energy is Moving energy  If we are talking about energy of something moving what factors exist that would give something more or less energy?

Kinetic Energy  KE = ½ mv 2  Kinetic Energy = ½ the mass times the velocity squared. 

Lets try some out  A man of 90kg is traveling in a car at 30 m/s. how much KE does the man have?

Now you try  Boxy with 7 kg of mass has 175 J of energy, how fast is he moving?
