Question
Which of the following has the same dimensions as that of momentum?
- AForce × TimeCorrect
- BForce × Distance
- CEnergy × Time
- DMass × Acceleration
Correct answer
Force × Time
Explanation
Momentum p = mv [MLT⁻¹]. Force × Time = [MLT⁻²][T] = [MLT⁻¹]. So Force × Time (impulse) has the same dimensions as momentum.
