are very important each time motion is involved!  Students have now created real-world examples that demonstrate each of Newton's Laws:
Law 1 - Inertia (An object in motion will stay in motion along its path unless an outside force acts upon it; an object in rest will remain at rest unless an outside force acts upon it).
Law 2 - Force = Mass x Acceleration (If a greater force acts on a smaller mass, that mass will accelerate faster; if a smaller force acts on a greater mass, the mass will accelerate slowly...or sometimes barely move at all).
Law 3 - Forces come in pairs (for each action there is an equal and opposite reaction).

In class this week, students will have the chance to record experimental data which shows how force impacts the distance a mass travels.
