What is the rate at which velocity changes? direction acceleration motion instantaneous speed

I believe the rate at which velocity changes is acceleration..(fingers crossed)

Hello there!

Actually, this would be know to be called (acceleration). When the velocity changes due to an object against speed or something that go against it, it wouldn't really matter what I would be, but the thing that would slow down the velocity would be changing the acceleration because the speed would be changing and no longer having the same speed as it had before.

Why is that? This would be because an object, or something is going against the velocity, and this would also be due to the acceleration.

Your (option b) = (acceleration).
