Question

How can an object (e.g. car) have zero velocity and nonzero (+/-) acceleration?

On top of this, how would this result in the object "speeding up?"

Answer 1

Imagine a circle.

Explanation:

Recall the velocity is displacement divided by time. So when you are going around in a circle, like a race track, you can be speeding up the whole way through but when you reach exactly where you started, your instantaneous velocity is `0m/s` as you displacement would be `0m` at that point.
