Year 1 Chapter 1: Momentum Flashcards
1
Q
How do you calculate momentum?
A
p = mv
2
Q
What is impulse?
A
The change in momentum.
3
Q
How do you calculate impulse?
A
I = mv - mu
4
Q
Derive impulse.
A
Substitute the suvat equation of acceleration into F = ma, then multiply both sides by t to form Ft = mv - mu
5
Q
What is the conservation of momentum?
A
Total momentum before impact = total momentum after impact.
6
Q
How do you calculate the conservation of momentum?
A
m1u1 + m2u2 = m1v1 + m2v2
