Question

kg m/sec is the unit of
1. Impulse
2. Angular acceleration
3. Capacity of condenser
4. Acceleration

Answer 1

Correct Answer - Option 1 : Impulse

The correct answer is Impulse.

• When a large force works on a body for a very small time interval, it is called impulsive force.
• An impulsive force does not remain constant, but changes first from zero to maximum and then from maximum to zero. In such a case, we measure the total effect of force.
• The impulse caused by a force during a specific time interval is equal to the body's change of momentum during that time interval.
• Impulse, effectively, is a measure of the change in momentum.
• The impulse of a force is a measure of the total effect of force.
• Impulse is a vector quantity and its direction is the same as that of force.
• SI unit of impulse is Newton-second or kg-m-s-1 and CGS unit is g.m/s
