Question

In which situation is an object accelerating?

A. A rock has a constant velocity of 0 m/s.
B. A motorcycle is parked on the side of the street.
C. A leaf's velocity remains 1 m/s as it falls from a tree.
D. A bicyclist's velocity changes from 2 m/s to 5 m/s as she travels down the street.

Answer 1

I would say D, because the object's speed moves up, therefore accelerating.
