Question 29: Centre of Mass and Rotational Motion

Question

Which of the following quantity represents the dimensions of momentum?

Accepted Answer

As we know that, Impulse = Force $$	imes$$ Time
= [MLT$$^{-2}$$] $$	imes$$ [T]
= [ML$$^1$$T$$^{-1}$$]
Momentum = Mass $$	imes$$ Velocity
$$p=mv$$
$$[p]=[m]	imes[v]=[\mathrm{M}][\mathrm{LT^{-1}}]=[\mathrm{ML^1T^{-1}}]$$
Thus, dimension of impulse represent dimensions of momentum.
