Momentum Flashcards
1
Q
Define linear momentum.
A
the linear momentum of a body is the product of its mass and velocity
2
Q
Define Impulse
A
the change in momentum
3
Q
state the law of consovation of momentum
A
the sum total or momentum of the bodies in a closed system is constant provided no resultant external force acts on the object
4
Q
state the equation of consovation of momentum
A
p = m1 u1 + m2 u2 +….
5
Q
what is newtons second law state in terms of momentum?
A
F=ma
F = (m/1) (v/t)
F = mv/t
F = p/t
6
Q
True or false if momentum is conserved over a collision the Ek is only conserved if the collision is elastic
A
True
