Momentum
I. Momentum  the property of a moving object that makes it difficult to stop.
Momentum = Mass x Velocity p = mv (kg•m/s) (kg)(m/s)
a) vector quantity
b) p has same direction as velocity
c) units  kg•m/s
[Flash] Kinetic Energy is conserved in perfectly elastic collisions
No
1) Relationship between force and momentum
When a force acts on a body it
Mathematical Relationship, F, p
p = mv
Δp = mΔv
F_{net} = ma
F_{net}t = mΔv
Δp = mΔv
F_{net}t = Δp
Force is the
time rate
Δp = Ft Force F, 'Follow through', t
The change in momentum that an unbalanced force produces on an object depends on ....
Noble and Greenough School H.S.
... how long the force acts on a body.
2) Impulse
Given this equation, what is another unit for momentum besides kgm/s?
Ns
