A body covers some distance along a curved path. Can it have a zero average velocity?

Open in App

Solution

Average velocity is defined as the ratio of total displacement by total time taken.
As average velocity depends on displacement and displacement can be zero if the object returns to initial position .

In this case, if the body moves along the curve in a circular path and reaches the starting point or initial position, the displacement is zero as source and destination is same. So the average velocity is zero.

Hence the body can have zero average velocity.

If a body travels at a uniform velocity of $u$ for $t$ seconds and at a different velocity of $v$ for the next $t$ seconds, what is the total distance covered in $2 t$ seconds?

Q. The correct match is:

List - I	List - II
a) A body covers first half of distance with a speed $V_{1}$ and second half of distance with a speed $V_{2}$	e) Average velocity is $\sqrt{\frac{g h}{2}}$
b) A body covers first half of the time with a speed $V_{1}$ and second half of the time with a speed $V_{2}$	f) Average speed is $\frac{v_{1} + v_{2}}{2}$
c) A body is projected vertically up from ground with certain velocity.Considering its total motion,	g) Average speed is $\frac{2 V_{1} V_{2}}{V_{1} + V_{2}}$
d) A body freely is released from a height h	h) Average velocity is zero

Q. Statement 1: On a curved path average speed of a particle can never be equal to average velocity.
Statement 2: Average speed is total distance travelled divided by total time. Whereas average velocity is, final velocity plus initial velocity divided by two.

The average speed of a moving body can never be zero but the average velocity of a moving body can be zero. Justify.
