Question

Which of the following statements is correct?

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

Answer 1

Answer: (D)

For a general rotational motion, angular momentum $\overrightarrow{L}$

and angular velocity $\overrightarrow{\omega}$ need not be parallel.

Answer 2

For a general rotational motion. Angular

momentum $\overrightarrow{L}$and angular velocity $\overrightarrow{\omega}$need not be parallel. For a general translations motions $\overrightarrow{p}$and $\overrightarrow{v}$are always parallel.
