Choose the correct alternatives :

For a general rotational motion, angular momentum `L` and angular velocity `omega` need not be parallel.

For a rotational motion about a fixed axis, angular momentum `L` and angualr velocity `omega` are always parallel.

For a general translational motion, mometum `p` and velocity `v` are always parallel.

For a general translational motion, acceleration a and velocity v are always parallel.

Text Solution

Verified by Experts

The correct Answer is:

A,C

From the study of theory, we know that for general rotational motion, angualr momentum `overset rarr(L)` and angular velocity `overset rarr(omega)` need not be parallel.
Again, for a general translation motion, linear momentum `overset rarr(p)` and linear velocity `overset rarr(v)` are always parallel.
This is because `overset rarr(p)` is directed along `overset rarr(v)` only.
