The dimensional formula for change in momentum is same as that for:
Correct answer: B. Impulse
- A. Force
- B. Impulse
- C. Acceleration
- D. Velocity
Explanation
The following is the solution:Impulse can be defined as "The sudden force acting on an object for a short interval of time".It is equal to ∆PThe units of both momentum and impulse are the same so their dimensional formulas are also same.

About Measurements
Physical quantities are expressed with SI base and derived units, while measurement limits are described through accuracy, precision, absolute and percentage error, and significant figures. Dimensional analysis checks equations, derives relationships and detects inconsistent units, but it cannot determine numerical constants or distinguish quantities with identical dimensions.
