(a) What does `|(dv)/(dt)|` and `(d|v|)/(dt)` represent? (b) Can these be equal?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
(a) `|(dv)/(dt)|` is the magnitude of total acceleration.
While `(d|v|)/(dt)` represents the time rate of change of
speed (called the tangential acceleration, a component of total acceleration) as `|v|=v.`
(b) These two are equal in case of one dimensional motion.
