Momentum Flashcards
1
Q
State the equation for momentum.
A
Mass * velocity
2
Q
What are the units for momentum?
A
Kg m/s or Ns
3
Q
What is the principle of the conservation of momentum?
A
If objects collide the total momentum before the collision is the same as the total momentum after the collision
4
Q
What are rules for calculating momentum?
A
- Always decide which direction is positive/negative
2. Always remember that the total momentum before will be the same as the total momentum after
5
Q
Give the conservation of momentum equation
A
m1u1 + m2u2 = m1v1 + m2v2
6
Q
What is impulse?
A
Change in momentum
7
Q
What is the equation for impulse?
A
mv - mu
OR
I= Ft
8
Q
What are the units for impulse?
A
Ns or kg m/s
