Question

Correct statment among the following is,

• A. For a general translation motion, momentum $\overset{ \rightarrow }{p}$ and velocity $\overset{ \rightarrow }{v}$ need not parallel.
• B. For a general rotational motion, angular momentum $\overset{ \rightarrow }{L} \, $ and angular velocity $\overset{ \rightarrow }{\omega } \, $ always be parallel.
• C. For a general translation motion, acceleration $\overset{ \rightarrow }{a}$ and velocity $\overset{ \rightarrow }{v}$ are always parallel.
• D. For a general rotational motion, $\overset{ \rightarrow }{\omega } \, $ need not be parallel.

Answer 1

Answer: (D)

For a general rotational motion, angular momentum $\overset{ \rightarrow }{L}$ and angular velocity $\overset{ \rightarrow }{\omega }$ need not be parallel. For a general translation motion $\overset{ \rightarrow }{p}$ and $\overset{ \rightarrow }{v}$ are always parallel.
