If a 5 mile stretch of a bus journey lasts 15 minutes, then the average speed over this stretch was 20mph. But undoubtedly the bus achieved greater speeds than this, and it also spent time sitting still in queues. So the simple answer to the question is 'yes'. Less trivially and more interestingly: unless velocity is actually constant, then an object's average velocity over a finite time interval - and hence any empirical measurement of its speed - must (nearly always) differ from the instantaneous velocity. As the time period grow closer to zero, the measured velocity will converge on the instantaneous figure, but will never reach it.

What is a instantaneous velocity?

Instantaneous velocity is the velocity of an object at a specific instant in time. It is the rate of change of position of an object with respect to time at that exact moment. This instant velocity may differ from the average velocity over a given time interval.


Does velocity differ from acceleration?

Acceleration is the rate of change of velocity.


How does acceleration and velocity differ?

Acceleration is the rate at which velocity is changing.


When an object moves with inconstant velocity does its average velocity differ from its instantaneous velocity?

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.


When average velocity and average speed is equal?

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


How is velocity different from average speeed?

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


When is the average velocity equal to average of velocity for an object?

Always.


Does average velocity and average speed have the same number?

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.


What is the best definition of velocity?

The speed of something in a given direction.


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 the relationship between average velocity and instantaneous velocity?

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.


What is average velocity's definition?

Average Velocity is displacement over total time.
