Conservation of Energy states ...

• Nature runs on energy.

• the warmer the activity the greater the amount of energy.

• energy is neither created or destroyed. It is just transferred or transformed.

• Kinetic energy is better than potential energy.

Newton's 1st law states ...

• The force applied to an object is equal to the the object's mass times the object's acceleration.

• For every action there is an equal and opposite reaction.

• An object at rest will stay at rest and an object in motion will stay in motion.

• An apple will hit you in the head when standing under an apple tree.
