The Law of Conservation of Energy states:
An object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by an outside force.
Energy can neither be created or destroyed, but it can change form.
For every action there is an equal and opposite reaction.
The force acting upon an object is equal to its mass times its acceleration; the greater the mass of an object, the more force is required to move it.
Wyatt is looking at the following diagram.

How can the gravitational potential energy of an object be increased?
By soaking it in water
By throwing it upwards
By weighing it on a spring scale
By raising it higher above the ground
At which point does the roller coaster have the greatest potential energy and why?
W, because it is the highest point
X, because it is the lowest point
