Momentum Flashcards
1
Q
what is the formula for momentum
A
p(momentum) = m * v
2
Q
what type of quantity is momentum
A
a conserved vector
3
Q
what is the formula for calculating two objects colliding
A
(m1+v1) + (m2 + v2) = (m1+m2) v3
4
Q
how do you calculate force from momentum
A
change in momentum/
time
5
Q
how do you work out change in momentum
A
mv - mu
6
Q
if there is a collision what is the rule about momentum
A
momentum is the same before and after
7
Q
If momentum is generated but starts at 0
E.g a gun shooting a bullet
what is the rule for momentum
A
final momentum will also equal 0
8
Q
What is the formula for momentum when starting at 0
A
(M1V1) + (M2V2) = 0
