Momentum And Impulse Flashcards
1
Q
SI until for momentum
A
p = kg.m.s^-1
2
Q
If the question mentions collision
A
They will test momentum
3
Q
Collision
A
And isolated event in which 2 or more bodies exert forces on each other over a relatively short period of time
4
Q
Change in velocity
A
🔺p =m(vf-vi)
5
Q
Fnet =
A
mvf-mvi/🔺t
🔺p/🔺t
6
Q
Net force
A
Rate of change of momentum
7
Q
Law of conservation of momentum
A
The total linear momentum of an isolated system remains constant
8
Q
I elastic collision
A
Kinetic energy is not conserved
Only momentum is conserved
9
Q
Elastic collision
A
Kinetic energy is conserved
10
Q
Impulse
A
The product of the net force acting on an object and the time for which it acts
Impulse = Fnet.🔺t
11
Q
SI unit for impulse
A
N.s
12
Q
Momentum
A
The product of the mass and velocity
p = mv
