Question

Are the measuring units of Force x time (Fxt) the same as the measuring units of momentum change (mvf - mvi)? Demonstrate it.

Answer 1

Yes

Step-by-step explanation:

The measuring units of force x time is the same as that of momentum change.

The product force x time is impulse and momentum change is mass x velocity.

The unit of force = N or kgm/s²

Time = s

Velocity = m/s

Force x time:

Unit = kgm/s² x s = kgm/s

Mass x (mvf - mvi ) = kg xm/s = kgm/s

So, we see that the units are the same
