# When did average velocity becomes zero? (2023)

## When did average velocity becomes zero?

If a trip starts and ends at the same point, the total displacement is zero, so the average velocity is zero.

Can average velocity ever be zero?

The average speed of a body in motion can never be zero whereas the average velocity of a body can have zero value.

When did final velocity is zero?

If a car starts from rest, its initial velocity is zero. If a projectile is tossed into the space, its initial velocity will be more than zero. If a car stops after applying the brake, the initial velocity will be more than zero, but the final velocity will be zero.

In which condition velocity becomes zero?

When two bodies travel in the same direction at the same speed, their relative velocity equals zero.

What does zero average velocity mean?

If a trip starts and ends at the same point, the total displacement is zero, so the average velocity is zero.

What is an example of average velocity zero?

(A)A car moving with an average speed returns to its original position. Hence, in this case the average speed is non-zero while the average velocity is 0. A car at rest has both average speed and average velocity zero since it covers no distance and no displacement and is stationary.

When did velocity change?

Velocity is a vector quantity. It has both magnitude and direction. Hence, it changes if the speed changes or the direction changes.

When did velocity become negative?

Negative Velocity: An object has negative velocity if its position is changing in the negative direction as time increases. If examining a graph of displacement vs. time, the velocity is negative whenever the graph has negative slope.

What happens when velocity becomes zero?

Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.

## Why can a body have 0 average velocity but not 0 average speed?

Since distance is also a scalar quantity and it wont be negative if we moves in opposite direction. It always adding irrespective of direction.So total distance travelled of a moving body can not be zero. So total average speed also cannot be zero and it will be nonzero if body is moving..

How can a body have zero average velocity but not average speed?

As it can be zero, so average velocity of the body can also be zero. But the average speed is the ratio of the total covered by the body to the time taken by it. As it can never be zero, so average speed of the body can also never be zero. Thus, the average velocity of a body can be zero but not its average speed. How did the velocity change?

The change in velocity occurs Due to change in direction of motion of the particle.

What is the velocity said to have changed?

A change in velocity is called acceleration.

How do you find average velocity?

Average velocity is calculated by dividing your displacement (a vector pointing from your initial position to your final position) by the total time; average speed is calculated by dividing the total distance you traveled by the total time.

Is average velocity ever negative?

Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction. Average speed does not indicate direction and can only be positive or zero.

Can velocity be zero or negative?

It can be positive or zero but can never be negative because a negative sign shows the direction and speed does not represent direction.

Does negative speed exist?

Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.

Is final velocity always 0 at max height?

When the object reaches a maximum height its velocity becomes 0 and starts falling in downward direction along the direction of acceleration due to gravity.

When the net velocity of the projectile is zero?

At a projectile's highest point, its velocity is zero. At a projectile's highest point, its acceleration is zero. The rate of change of the \begin{align*}x\end{align*} position is changing with time along the projectile path.

## Is velocity ever zero in projectile motion?

a. Is the velocity ever zero? The velocity is never zero in the case of a projectile launched at a nonzero non-vertical angle with respect to the horizontal, or in the case when the projectile is launched horizontally from a certain height.

Why is velocity zero at extreme?

When the mass is at the maximum displacement position, velocity is zero because the mass is changing direction. At the position of maximum displacement, the restoring force is at its greatest - the acceleration of the mass will be greatest.

How is velocity 0 at highest point?

Yes, due to -ve acceleration along vertical direction velocity keep on decreasing and at the highest it becomes zero.

When can velocity be zero but acceleration is not?

It is possible that the acceleration of a particle is non-zero and velocity is zero at the same instant. For example, if a ball is thrown up then at the highest point, velocity is zero but the acceleration is non-zero.
