10. What is Kinetic Energy?
Kinetic energy is the energy of motion that is released from stored energy.

11. Examples Object rolling down hill Arrow released from bow
Muscles moving
A car moving

12. Examples Potential Energy when up ready to be released.
Kinetic Energy when it moves up in down by energy from string

13. Examples
For the biker the bottom of the hill is a point of potential energy
Going up the hill energy is coming in which means the biker is going through kinetic energy.
Biker waiting on top of the hill to go down is potential energy.
Going down the hill energy is going out which means the biker is going through kinetic energy.
For the biker the bottom of the hill is a point of potential energy
