Roller Coaster Forces | HowStuffWorks

When you ride a roller coaster, all the forces we've discussed are acting on your body in different ways. Newton's first law of motion states that an object in motion tends to stay in motion. That is, your body will keep going at the same speed in the same direction unless some other force acts on you to change that speed or direction.
