Question

1. Is impulse the same as momentum or is it different?  Explain.

2. How are the units for momentum  compared to the units for impulse?

3. There is a formula that describes the relationship between impulse and momentum, what is it?  Write it down below and briefly explain what it means.

Answer 1

Solution)

1) Impulse and momentum are different.

Impulse is basically defined as the change in momentum.It is represented by symbol J. Also, the net force acting on the system for the time for which it acts.

And momentum is defined as the product of mass of an object multiplied by velocity. Its symbol is P.

2) Unit of impulse = newton-seconds

Unit of momentum = kilogram metre per second

(Algebriacally, units are same)

Also, impulse =force *time

3) J=Δp

Relation Formula

F = m • a
F = m • ∆v / t

F • t = m • ∆v

Which means impulse equals change in momentum.
