Group of answer choices
The velocity direction is changing across the motion trajectory, but the acceleration direction remains the same.
The direction of both velocity and acceleration are changing across the motion trajectory
For a free fall object(the horizontal component of the initial velocity is zero), its velocity is zero when it reaches maximum height, but its acceleration is not zero at the same time.
