Section 2: Newton’s Laws

Newton’s 1st law:

Inertia:

Demo: Hammer and BlocksTable Cloth:Balloon and Marbles:

Reflection Questions

1) 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?

2) 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.
