Answer 1

Answer :

N-s is the unit of momentum.

Explanation :

As per newton's second law of motion, Force is defined as the rate of change of linear momentum$.$

• F = dP/dt

F denotes force

dP denotes change in momentum

dt denotes change in time

➝ F = dP/dt

➝ dP = F × dt

We know that,

Unit of force : N

Unit of time : s

Therefore, Unit of momentum will be N-s.

Answer 2

$\sf \underline{Answer :}$

Newton-second is the SI unit of momentum

$\sf \underline{Explaination :}$

The Newton's second law of motion states that the rate of change of momentum is directly proportional to the applied force

Mathematically ,

f ∝ ΔP/t

f = kΔP/t

Where , k = constant = 1

f = ΔP/t

It can be written as ,

ΔP = f × t

$\therefore$ The SI unit of momentum is Newton-sec
