Question

Unit of Impulse is the same as that of?
1. Force
2. Mass
3. Change in Momentum
4. Pressure

Answer 1

Correct Answer - Option 3 : Change in Momentum

The correct answer is option 3) i.e. Change in momentum.

CONCEPT:

• Impulse (I): It is the force applied for a certain time duration to cause a change in the momentum of a body.
  • Its SI unit is Ns.

It is the product of force (F) and time (t) for which the force is applied i.e.

I = F × t

EXPLANATION:

• The SI unit of impulse is the newton second (Ns), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kgm/s).

• The SI unit of mass is the kilogram(kg).
•  The SI unit of pressure is the pascal(N/m²).
