Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.

No. Its velocity, average velocity and instantanous velocity will all be the same at any (or every) time an investigator makes an observation.


No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.


Acceleration is the rate of change of velocity.


Acceleration is the rate at which velocity is changing.


For the instantaneous value of average velocity, average speed and average velocity are equal.


average velocity means change in displacement and time interval ratio is called as average velocity average velocity what is the velocity at particular instant of time


Generally it is a Yes. Instantaneous velocity is the exact velocity at a particular time in the course of the movement. However, average velocity is the average of all the instantaneous velocity over a period of time. It is also known as speed in everyday life. As a result, the movement of an object over a time period under varying velocity denotes a varying instantaneous velocity which could be different from the average velocity. It is however, possible that the instantaneous velocity equates to the average velocity at a certain point over the duration of movement. For example, a ball is traveling at instantaneous velocity of 99m/s at t=1s , 100m/s at t=2s and 101m/s at t=3s. the average velocity over the 3s period is hence 100m/s which coincides with the instantaneous speed at t=2s.


Velocity indicates direction in addition to speed.


Velocity is speed and its direction. Average velocity is average speed and its direction.


what is magnitude of average velocity


Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.


Average velocity is the distance traveled divided by the time it takes to travel that distance. Average velocity is also called "velocity".


average velocity= displacement/ time


yes, velocity is speed with direction; average speed has no direction, bit average velocity does


velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.


No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).


Average velocity = displacement over time


The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.


To calculate Average velocity: ( Vf - Vi ) / t Where Vf is Final Velocity Vi is Initial Velocity t is Time


At a small time interval, the average velocity is approximately equal to the instantaneous velocity. However, the values of the average velocity and the instantaneous velocity approach each other , as the length of the time interval is decreased more and more.


The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT 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.


Simply put,acceleration is got when velocity changes with time while velocity is when speed changes with time.


The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity.


Average velocity is zero if the displacement is zero. Average velocity = Displacement/Time = 0/Time = 0.
