1. Year 10 Pathway C Mr. D. Patterson 1

2.  State that energy can be transformed without loss  Apply energy transformation to simple situations 2

3. 3

4.  1) Energy can not be created or destroyed 4 The ball is raised, gaining potential energy (E = mgh) The potential energy was not ‘created’ It came from the energy stored in the muscles

5.  2) Energy can be transformed from one type into another 5 The potential energy of the ball transforms into kinetic energy

6.  3) Energy can be transferred from one object to another 6 As the first ball collides with the others, it stops. The ball at the end moves off at the same speed as the first. The kinetic energy has been transferred.
