anonymous · Answer

impact- N
impulse- kg • m/s?

anonymous · Answer

impact = force
impulse = force*time = change in momentum 

P.S  your units are absolutely right!

alright, thanks!!!

Impact force is specifically for forces over a short period of time. It is still a force and has the same unit as force: example kg m /sec^2

Impulse force is force multiplied by time duration and is similar to momentum.
Impulse is change of momentum and has the same unit as momentum: example kg m /sec

Thus the different is impact is related to acceleration (m /sec^2), impulse is related to velocity (m /sec).
