Momentum And Impulse Flashcards
1
Q
Momentum
A
The product of an objects mass and its velocity
P=mv
2
Q
Newton’s send law in terms of momentum
A
The net force acting on an object is equal to the rate of change of momentum of the object in the direction of the net force.
Fnet=ΔΡ/ΔΤ
3
Q
Impulse
A
The product of the resultant force acting on an object and the time the resultant force acts on the object.
ΔP=FnetΔT
4
Q
Closed system
A
A system on which the resultant external force is zero
5
Q
Principal conservation of linear momentum
A
The total linear momentum of a closed system remains constant.
ΣΡbefore =ΣΡafter
6
Q
Elastic collision
A
I collision where the energy is conserved.
Ekbefore=Ekafter
7
Q
Inelastic collision
A
A collision where energy is not conserved
