Choose the correct alternatives

Question

Choose the correct alternatives (A) For a general rotation motion, angular momentum L and angular velocity w need not be parallel (B) For a rotational motion about a fixed axis, angular momentum L and angular velocity ω are always parallel (C) For a general translational motion, momentum p and velocity v are always parallel. (D) For a general translational motion, acceleration a and velocity v arc always parallel

Tardigrade Admin · Accepted Answer

From the study of theory, we know that for general rotational motion, angular momentum

L

and angular velocity

ω

need not be parallel.
Again, for a general translational motion, linear momentum

p

and linear velocity

v

are always parallel. This is because

p

is directed along

v

only.

Q. Choose the correct alternatives

For a general rotation motion, angular momentum L and angular velocity w need not be parallel

For a rotational motion about a fixed axis, angular momentum L and angular velocity $ω$ are always parallel

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

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

From the study of theory, we know that for general rotational motion, angular momentum $L$ and angular velocity $ω$ need not be parallel.
Again, for a general translational motion, linear momentum $p$ and linear velocity $v$ are always parallel. This is because $p$ is directed along $v$ only.
