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.

∙ 12y agoOf course. When you're sailing along in the car on the highway with the
"cruise control" on, and the ride is smooth as silk and the speedometer is
pointing at ' 60 ' and never moving, your average and instantaneous speed
are equal, until you do something to change your speed.
And if the road is straight and you keep moving in a straight line, then the
same statement is true of your velocity, as well as your speed.

∙ 8y agoNo it does not. If the velocity is 10 m/s for 10 secs and 0 for another 10 secs, then the average is 5 m/s which is non-zero over the 20 second period. But the instantaneous velocity is zero for the period from 10 to 20 seconds.

the remaining 14 hours in a motel, then the instantaneous 70 or 75 mph that
you frequently hit while on the interstate during the day is most definitely greater
than your average speed for the trip.

∙ 15y agoNo. Its velocity, average velocity and instantanous velocity will all be the same at any (or every) time an investigator makes an observation.
Wiki User
∙ 15y agoYes, if the instant in question is near the end of the objects travel, but no if it is at the very begining, unless the object's velocity is somehow increasing while it is in movement.
Wiki User
∙ 15y agoYes. Velocity is speed and direction so it can change velocity by changing direction.
Wiki User
∙ 12y agoAverage 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.
Wiki User
∙ 11y agoNo. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.

How does velocity differ from speed?
Velocity indicates direction in addition to speed.
Does average velocity have a direction associated with it?
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
Is Distance the magnitude of average velocity?
No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).
How does velocity differ from acceleration?
Acceleration is the rate of change of velocity.
What is instantaneous velocity of a body in terms of its average velocity?
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.
How does acceleration and velocity differ?
Acceleration is the rate at which velocity is changing.
Does velocity differ from acceleration?
Acceleration is the rate of change of velocity.
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.
How does velocity differ from speed?
Velocity indicates direction in addition to speed.
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.
What is average velocity?
Average velocity is def.ined as the ratio of total displacement to total time taken.
Does average velocity have a direction associated with it?
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
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.
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.
