All these are true about impulse except

Here are the solutions to questions 2, 3, and 4.

2. All these are true about impulse except

Impulse ($J$) is defined as the change in momentum of a body. It is also the product of force and the time interval over which the force acts ($J = F \Delta t$). Its unit is Newton-second (Ns), which is equivalent to kg m/s.

• A. change in momentum of a body: True.
• B. its unit is Ns: True.
• C. product of force and time: True.
• D. change in acceleration of a body: False. Impulse is related to the change in momentum (mass times velocity), not directly to the change in acceleration
