Question

6. Do instantaneous velocity and instantaneous acceleration have the same magnitude? Give reason. -

Answer 1

Answer:

Instantaneous speed is the magnitude of instantaneous velocity. Instantaneous velocity is a vector. Instantaneous speed is the magnitude of instantaneous velocity. It has the same value but is not a vector so it has no direction.

Explanation:

____Instantaneous velocity. The rate of change of displacement of an object in a particular direction is its velocity. ... The magnitude of instantaneous velocity equals the instantaneous speed. This happens because, for an infinitesimally small time interval, the motion of a particle can be approximated to be uniform.

Answer 2

Instantaneous speed is the magnitude of instantaneous velocity. Instantaneous velocity is a vector. Instantaneous speed is the magnitude of instantaneous velocity. It has the same value but is not a vector so it has no direction.
