A ball is launched upward from the ground. The diagram shows the location of the ball at 1-second
intervals.

Acceleration: Down at all points

Velocity: Up (A,B,C,D), Zero (E), Down (F,G,H,I)

Explanation:

ACCELERATION:

The ball is under the action of gravity at all times. Hence, the direction of acceleration will be downward at all points. Because, the gravitational force acts downward and its acceleration will always be downward as well.

VELOCITY:

The direction of velocity depends upon the direction of motion. Therefore, The direction of velocity will be up during upward motion at following points:

Points A,B,C,D (Up)

At the highest point, the ball stops momentarily. Hence, the velocity is zero at this point.

Point E (Zero)

And the velocity direction becomes down for the rest of the motion.

Point F,G,H,I (Down)

i believe the answer is electric potential.
