Yes - for example, if an object moves in a circle.

Yes, it is possible. Average velocity takes into account both the magnitude and direction of motion, and can be zero if the particle moves back and forth. However, average speed only considers the total distance travelled over time, and can be non-zero even if the velocity is constantly changing.

What is the average velocity of a particle when it returns to the straight point?
The average velocity of a particle when it returns to the starting point is zero. This is because velocity is a vector quantity that includes both magnitude and direction, and returning to the starting point means the displacement is zero, resulting in an average velocity of zero.
Equation for calculating average velocity from displacement and time interval?
Average velocity can be calculated by dividing the displacement (change in position) by the time interval. The formula for average velocity is average velocity = (final position - initial position) / time interval.
What is instantaneous velocity of a body in terms of its average velocity?
The instantaneous velocity of a body represents its velocity at a particular instant in time, while the average velocity is calculated over a certain time interval. To find the instantaneous velocity from the average velocity, you can take the limit as the time interval approaches zero in the average velocity calculation. Mathematically, this can be represented as the derivative of the position function with respect to time.
Is Acceleration is the magnitude of average velocity true or false?
False
When is the average velocity is equal to the instantaneous velocity?
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
When Velocity of particle equals average velocity equals instantaneous equals speed is possible?
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
What is the average velocity of a particle when it returns to the straight point?
The average velocity of a particle when it returns to the starting point is zero. This is because velocity is a vector quantity that includes both magnitude and direction, and returning to the starting point means the displacement is zero, resulting in an average velocity of zero.
What is the average velocity of the particle from rest to 9 seconds?
The answer will depend on its acceleration.
Is ta possible for an object to have average velocity equal to its instantaneous velocity?
Yes, yes it is
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
What are Drift velocity and momentum relaxation time?
Drift velocity refers to a particle's average velocity being influenced by its electric field. Momentum relaxation time is the time required for the inertial momentum of a particle to become negligible.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
What is the average velocity between 12.00 and 15.00 seconds?
To find average velocity, you need to know the displacement. If you knew displacement, average velocity would be found by: V = Displacement / time
Is it possible for a body to have average speed but zero average velocity give reason and example?
Yes, it is possible. This can happen when an object changes direction but ends up at its starting point. For example, if a person walks a certain distance in one direction and then walks back the same distance, their average speed over the entire trip could be constant, but their average velocity would be zero since displacement is zero (ending at the same point).
Can the average velocity of a particle be zero when its average velocity is not zero?
All experimental observations until now are in unanimous agreement that such an event cannot occur. Within the limits of our ability to measure the relevant quantities to date, it appears to be impossible.
Can the average velocity of a particle be zero but not its average speed?
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
When is the average velocity equal to average of velocity for an object?
Always.
