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.
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.
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.
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.
Instantaneous velocity and average velocity are not the same. Instantaneous velocity is the velocity at a specific moment in time, while average velocity is the total displacement over a given time interval. In general, they will not have the same value unless the motion is at a constant velocity.
False
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.
Acceleration is the rate of change of velocity.
Acceleration is the rate at which velocity is changing.
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.
For the instantaneous value of average velocity, average speed and average velocity are equal.
Velocity is speed and its direction. Average velocity is average speed and its direction.
Always.
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.
The speed of something in a given direction.
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.
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.
Average Velocity is displacement over total time.
