1. Carefully set-up a ramp
2. Try it out and make adjustments so the car will travel at a high speed after it has left the ramp
3. Set-up a small block that will bring the car to a stop
4. Finally begin testing the distance the coins travel.

11stst Law of Motion Law of Motion
An object at rest tends to stay at rest An object at rest tends to stay at rest and an object in motion tends to stay and an object in motion tends to stay in motion until an outside force acts in motion until an outside force acts on it.on it.
