# Momentum A2! help???? watch

1. Can someone help me how to use the momentum of conservation in solving problems and show me a formula which I can use
2. I dont know if conservation has momentum...but momentum is certainly conserved!

Momentum before collision=momentum after collision

and...

momentum(p)=mass(m)*velocity(v)
3. It might be worth looking at some Mechanics 2 (A-Level Maths) papers because they have quite a few questions on momentum and impulse.
4. http://antonine-education.co.uk/Phys...4/Overview.htm

That guy can! Legend.
5. For questions concerning the principle of conservation of momentum, take one direction as positive. Work out the total momentum in that direction before the interaction , then work out the total momentum in the other direction and minus this from the original value.

Now you can substitute and solve to find any single value for after the interaction. Usually, they give you all the data except one value and you have to work that out. From there it's just some simple algebra.
6. Thanks guys! Jeester thank you so much! i will give u the rep++
Aper son your rep++ will come tomorrow

LOL definetly deserve a rep+ remind me on the day after tomorrow
8. Jeester sorry man i know you helped me alot but my reep+ won't make a difference to your reputation lol
so the rep+ has to go to aper_son

Good! Momentum's easy as long as you remember to take into consideration the direction of the particles (etc) and can do scale drawings.

I'd be so happy if the entire exam was on momentum
