1.6) Momentum Flashcards
1
Q
Momentum =
A
Mass x velocity , N.s
2
Q
Law of conservation of momentum
A
Total momentum before collision = total momentum after collision
3
Q
Impulse is
A
Change in momentum
Ft = (mv-mu)
4
Q
Explain how rubber floor reduces injury to child on a seesaw
A
When child hits flood causes change in momentum
Change in momentum is over a longer time
Force = rate of change of momentum
So less force on child
