More Stuff on Momentum

This week in Physics, we learned more about momentum.  On Wednesday we were suppose to do a lab about collisions to help us learn more about momentum, but I was sick on that day, so I'm not exactly sure how to explain anything about collision.  But, I can explain a little bit about the Law of Conservation of Momentum.  This law states that momentum cannot be created nor destroyed, it only changes forms, momentum in then will equal momentum out.  From this week, I learned the momentum is a vector/  To find momentum you must multiply the mass of an objec by its velocity (P = mv).  The units we use in this equation are kg m/s.  I also learned about impulse and how it contributes to momentum and force.  Impulse is the change in momentum (delta P).  This is then plugged into the equation of force, which equals the change in momentum/change in time (delta P/delta T).  This is what I learned this week in Physics.
