Average Velocity vs. Delta Velocity

[hjapl]

Whats the difference between average velocity and delta velocity? I understand the formulas (ie. Vave = delta displacement/delta time) but I don't understand why you would use one over the other and what the difference is. Thanks for the help.

Do you mean what is the difference between average and instantaneous velocity?

They are the same thing.

Usually a "delta velocity" is used to denote change in velocity, not average velocity. It's how much the velocity has changed over a given time interval. Just like delta displacement is how much you've moved over a given time interval.
