Skating Physics: Inertia and Motion

Toward the direction that reduces the object's potential energy as rapidly as possible.

Work is equal to the force multiplied by the distance, where force and distance are in the same direction.

The force and distance are different on a shallow ramp versus a steep ramp, but the work done is the same.
