Momentum Flashcards
1
Q
what is impulse
A
effect of force acting over time to change the momentum of an object
2
Q
what is the formula for momentum
A
momentum = mass x velocity
3
Q
what is momentum
A
how hard it is to stop something
4
Q
what is the law of conservation of momentum
A
In the absence of external forces (such as friction), the total momentum of a system remains the same
This means that in a collision, the sum of the momentums before the collision will be the same as the sum of momentums after the collision
5
Q
equation for the conservation of momentum
A
(m1 x v1) + (m2 x v2) = total mass x V
6
Q
what are the two formulas for impulse
A
impulse = change in momentum impulse = force x time
7
Q
what is the formula for change in momentum
A
change in momentum = MVinitial - MVfinal
