Electrical Engineering XYZ MCQs

Newton-second is unit of which Quantity:

- Acceleration
- Velocity
- Impulse
- Speed

Correct answer: 3. Impulse

Explanation: Impulse is defined as the change in momentum of an object when a force is applied over a period of time. The mathematical expression for impulse (I) is given by:

I = ๐นรฮ๐ก

Where

- ๐น is the force applied
- ฮt is the time duration over which the force is applied
