1. My experiences and observations of forces and the laws of motion

2. Inertia: A body at rest tends to stay at rest unless acted on by an outside force. On my dad’s farm the tractor stays at rest until someone starts the engine and drives it around.

3. Inertia: A body in motion tends to stay in motion unless acted upon by an outside force. I watched Mike Modano shoot the hockey puck. It kept going in a straight line until it slammed into the goal net. That changed its motion to a new direction and then it stopped.

4. For every action there is an equal and opposite reaction In my uncle’s factory, I saw one gear turn one way which caused another gear to turn the other way.

5. Force = Mass x Acceleration We went to the beach to jump in the waves. The big waves hit us hard enough to knock us down. The small waves only made us wiggle a little bit.
