How is average velocity different from instantaneous velocity ?

Text Solution

Verified by Experts

Average velocity:
i)It is defined as ratio `Deltax` displacement to the time interval `Deltat`. `barv_(x)=(Deltax)/(Deltat)-(x_(2)-x_(1))/(t_(2)t_(1))`.
(ii)Average velocity is independent of the path followed by the particle between initial and final positions.
Instantaneous velocity:
i)The velocity of a particle at a particular instant of time is known as instaneous velocity .
i.e., `v_(x)underset(Deltato0)(Lm)(Deltax)/(Deltat)=(dx)/(dt)`
ii)Instantaneous velocity is the rate of change of position with time.

When a particle moves with constant velocity its average velocity, its instantaneous velocity and its speed all are equal. Is this statement true or false ?

When a particle moves with constant velocity, its average velocity, its instantaneous velocity and its speed are all equal. Comment on this statement.

Assertion: When a particle moves with constant velocity its average velocity, its insttantaneous velocity and its speed are all equal in magnitude. Reason: If the average velocity of a particle moving on a straight line is zero in a time interval, then it is possible that the instantaneous velocity is never zero in the internal.
