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".

A distance-time graph shows the movement of an object with respect to time. The average slope between any two points on the graph is equal to the average velocity of the object between those two points. The instantaneous slope (or derivative) at a point on the graph is equal to the instantaneous velocity of the object at that point.

It's equal to the change in velocity (final velocity - initial velocity).

The area under an acceleration-time graph is equal to the object's velocity (not change in velocity).

That's the velocity at any time.

When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.

Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.

An object's average velocity is equal to its instantaneous velocity when the object is moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, resulting in the average velocity over a period of time being equal to the instantaneous velocity at any given moment within that period.

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

In uniform motion.

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.

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".

Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.

Acceleration is the derivative of velocity (a=dv/dt). If you are not familiar with calculus then it would be sufficient to say that the slope of the line tangent to the graph, only touches at one point, is equal to the instantaneous acceleration.

Average speed is calculated by dividing the total distance traveled by the total time taken. Instantaneous speed, on the other hand, is the speed at a specific moment in time. They can be equal in situations where speed is constant over time, but in most cases, they will differ because instantaneous speed can vary as the object moves.

Acceleration.
