Momentum and Impulse Flashcards
1
Q
momentum
A
p = mass x velocity (vector quantity)
2
Q
law of conservation of momentum
A
whenever two or more objects interact, their total momentum remains unchanged. sum of momentum before = sum of momentum after
3
Q
calculations with momentum
A
say east is positive
4
Q
what is impulse
A
change in momentum,
can be calculated by comparing momentum at two points in time
5
Q
formula for impulse
A
mv - mu
f x deltaT
