Question

4. Impulse is measured in .........​

Answer 1

Impulse is measured in N.s (newton-second) or kg.m.$s^{-1}$

What is an impulse?

• For a constant force acting on a body for an interval of time, the product of the force and the time interval is the impulse of the force, or simply, the impulse.
• The change in momentum of a body is equal to the impulse of the force acting on it.

Answer 2

Impulse is measured in Newton-seconds.

What is impulse?

• In the field of physics, an impulse can easily be described as an integral part of force (F) which is observed in a specific time period of time (t).
• The change in the momentum of an object when a force is applied for a specific time is the impulse of the object.
• As force is measured in Newtons and the measuring unit for time is Seconds, hence the impulse will be measured in Newton-seconds.
