The dimensions of momentum are the same as that of:
Correct answer: C. Impulse
- A. All of these
- B. Power
- C. Impulse
- D. Planck's constant
Explanation
The dimensions of momentum are [M1L1T-1] corresponding to its formula mv. The dimensions of impulse are the same as momentum as it is actually the change in momentum. The dimensions of impulse are also [M1L1T-1] corresponding to its formula I = F x t.The dimensions of power are [M1L2 T-3]. The dimensions of Planck's constant are [M1L2T−1], the same as that of angular momentum.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
