  3. Reflection Questions • The first law of motion states that no forces is required to maintain motion. Then why do you have to keep peddling to maintain motion? • An elephant and a mouse have the same weight of zero in space. It they were both moving at the same speed toward you, which would have the greatest effect? Explain.
