What is the differens between average velocity and instant velocity?

Think of average velocity as "overall" velocity. For example, if I walk down the block (let's say it's a distance of 100 meters), and it takes me 5 minutes, my AVERAGE velocity is just:
v_ave = Δx/Δt
where Δx is the change in position and Δt is the elapsed time.
v_ave = (100 m) / (5 min)
v_ave = (100 m) / (300 sec)
v_ave = (1/3) m/s
But instantaneous velocity is a different concept: let's say for a while I walked, then I jogged, then I stopped, then I sprinted, then I walked. The overall trip still ended up taking me 5 minutes, so my average velocity is just as I've calculated it above, but my INSTANTANEOUS velocity changes as I change speeds at any given time in between.
Hope this helps!

What is the best definition of velocity?
The speed of something in a given direction.
Difference between instantaneous and average velocity?
average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)
When is the instantaneous velocity equal to avg 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.
Is Average velocity the slope of the line tangent to the curve on a velocity time graph at a specific instant of time?
No, it is instantaneous acceleration.
Find average acceleration and instanious acceleration?
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
Consider the instantaneous velocity of a body this velocity is always in the direction of what the net force at that instant the least resistance at that instant or the motion at that instant?
the motion at that instant
When an object is in motion how can the average velocity be calculated?
it can be calculated at a particular instant as it is total displacement in given time
What is instantaneous velocity or speed?
It is the speed or velocity at a particular instant.
When an object and acceleration is zero at some instant t in time its velocity is?
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
How fast is an object moving at the instant it hits the top of its trajectory?
Assuming that there is no velocity in the horizontal direction, then the velocity at that instant is zero.
What's the difference between instantaneous velocity and instantaneous acceleration?
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
How fast velocity is changing at a specific instant?
Acceleration is the rate of change of velocity.
