When an object moves with constant velocity does its average velocity during a time interval differ from its instantaneous velocity at any instant?
No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.
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.
When is the average velocity is equal to the instantaneous velocity?
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.
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.
Can the average velocity of the body be the same as instantaneous velocity?
Yes, the average velocity of the body can be same as the instantaneous velocity at a small time interval.The values of the average and the instantaneous velocities approach each other , as the length of time interval is decreased.
When is the average velocity equal to the instantaneous velocity?
When an object is in constant motion (when there is no acceleration). At any point in that motion the average and instantaneous velocities will be the same.
Would instantaneous velocity yield the same value as average velocity?
Only if the velocity is constant.
Where must the average velocity for an interval be plotted on a velocity-time graph to represent an instantaneous velocity?
at half time intervals.
When will the average acceleration be equal to the instantaneous acceleration?
Mainly when the velocity is constant.
What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
When is an object's average velocity equal to its instantaneous velocity?
If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.
What are the difference of instantaneous velocity and average velocity?
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
