| Term | Definition |
|---|---|
| Momentum | characteristics of a moving object that is related to the mass and velocity of an object |
| what does newton call momentum? | quality of motion |
| What is an object's momentum? | it can be determined by multiplying the mass by its velocity |
| what is momentum's formula | m=mass/velocity |
| What is momentum's SI unit | kg*m/s |
| Law of Conservation of Momentum | in the absence of outside forces like friction the total momentum of objects that interact do not change. |
| Non Sticky colllisions | if one car is hitting a moving car from behind the car that is going faster before the collision will slow down and the other one will sped up |
| Sticky collosions | if one car is parked and another runs into it, after they collide they stick together ant the cars share the momentum and the total momentum of the two cars stays the same |
| Total Momentum | of any group of objects remains the same or is conserved unless outside forces act on the objects |
