**Kinetic energy**KEep moving!**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 mv2 Kinetic Energy = ½ the mass times the velocity squared. http://youtu.be/vl4g7T5gw1M**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?
