Differentiate between moments and momentum

1 answer:

5 0

Answer: Momentum applies to objects in motion and is the product of mass and velocity. It is not the energy, but the variables are the same. By contrast, "moment" is an expression of the "rotational force" caused by a force acting at some distance from a fulcrum.

Two homogeneous bodies of the same volume

Answer:

No, it is not necessary for them to have same mass.

Explanation:

Let both bodies have a density d1 and d2 respectively.

Since their volumes are equal V1 = V2

we know that, https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%7D

Hence, d1 = and d2 =

Taking the ratio of densities,we get

This implies that unless the bodies have same densities, the mass of the two bodies will not be same.
