In a collision, is the net impulse experienced by an object equal to its momentum change?

Answer 1

Yes. Impulse is defined as the change in momentum over an arbitrary time interval, or equally as the average force times the difference in time.

#J = Deltap# #J = F_(avg)*(Deltat)#

You can see from the second equation why the unit of impulse is typically the Newton-second. (#N*s#)

If you know an object's initial momentum and its final momentum, the impulse is given by the difference between the two values.

#Deltap = p_(f) - p_(i)# #J = p_(f) - p_(i)#

Yes, in a collision, the net impulse experienced by an object is equal to its momentum change. This is based on the principle of conservation of momentum, which states that in a closed system, the total momentum before a collision is equal to the total momentum after the collision. Therefore, the change in momentum of an object during a collision is equal to the net impulse exerted on it.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
