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 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.

No.Average 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.

Only if the velocity is constant.

No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.

BecuZ average is the same limit and the other is nesting velocity

velocity is just a general term for speed (it could be average velocity or instantaneous velocity). Instantaneous velocity/speed (same thing) is the speed at that second. If you are familiar with calculus, it is the derivative of the position graph. Whereas average velocity is how fast the object is going in, for example, 1 hour, it is the speed that is maintained the whole hour (or the average) Instantaneous would be that at the second, at for example t=1.425, the speed is 24m/h . something along those lines

Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.

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".

No. Its velocity, average velocity and instantanous velocity will all be the same at any (or every) time an investigator makes an observation.

In that case, the average speed is the same as the instantaneous speed.

They are the same thing, however velocity is 'in a given direction', speed is in any direction.

Of 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.

Yes, But in uniform motion only.

Never.Average velocity is total displacement (final position minus initial position) divided by the total time: vave = (xf-xi)/tAcceleration is the rate at which your velocity is changing or change in velocity over time: a= (vf-vi)/tThese two quantities may have the same numerical value but will never have the same units.Average velocity for a trip can equal instantaneous velocity at a certain point during the trip, however, at any time during a trip in which the velocity is constant or at half way through the total time of a trip where the acceleration is constant.

Average and instantaneous speed are the same when the speed is constant during the time period you're interested in.

Speed has only size. Velocity has size and direction.If three drivers are driving their cars at 50 mph headed north, 50 mph headed south, and50 mph headed east, their speeds are all equal, but their velocites are all different.Instantaneous speed is the speed at an instant in time. A point on the edge of an LP record hasthe same instantaneous speed whenever you look at it.Instantaneous velocity is the velocity ... speed and direction ... at an instant in time. A point on theedge of an LP record has a different instantaneous velocity every time you look at it. Even thoughthe speed is always the same, the direction keeps changing.

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.

Average speed = (total distance) / (total time) = (v1t1 + v2t2) / (t1 + t2)

Yes, if the instantanious velocity is constant.

The magnitude of both can be the same.

Instantaneous velocity mean change of displacement in extremely small amount time. (in math way, taking[ lim t--->0 (change in displacements/change in time) ]. instantaneous speed is the same expect displacement change to distance. So,because of very very small change in time, magnitude of distance and displacement will be same for any direction the object is moving.

different on constant and instantaneous speed

Yes. The average of a list of copies of the same number is the same number.
