Question

change in momentum is given by
force * time
force * mass
force * velocity
force * distance

Answer 1

Change in momentum is given by force * time.

But why?

• First of all, let's define force : Force is define is the $\rm inst antaneous$ rate of change of momentum with respect to time.

• Let change in momentum be ∆P, force be F and time be t.

So, mathematically, force is represented as:

$F = \dfrac{\Delta P}{t}$

$\implies \Delta P = F \times t$

So, change in momentum is actually the product of force and time.
