1. Define momentum.
2. Calculate momentum.
3. Explain the law of conservation of momentum.
Inertia is the property of mass that resists change. Therefore, it is safe to say that as the mass of an object increases so does its inertia. Weight is the measurement of resting inertia and momentum is the measure of inertia at a certain velocity. We all know that at the same forward velocity it would be harder to stop a rolling car that a rolling bike. Common sense tells us that the mass of the car makes it more difficult to stop. Here are some simple rules for momentum..
