A ball is tossed vertically upward.When it reaches its highest point (before falling back downward)
A) the velocity is zero, the acceleration is directed downward, and the force of gravity acting on the ball is directed downward.
B) the velocity is zero, the acceleration is zero, and the force of gravity acting on the ball is zero.
C) the velocity is zero, the acceleration is zero, and the force of gravity acting on the ball is directed downward.
D) the velocity and acceleration reverse direction, but the force of gravity on the ball remains downward.
E) the velocity, acceleration, and the force of gravity on the ball all reverse direction.

At the highest point of its trajectory, a ball's velocity is zero because it stops for an instant before falling back down. However, acceleration due to gravity remains directed downward at approximately 9.8 m/s^2, and the force of gravity also continues to act downward on the ball. This is because gravity is a constant force acting on objects near Earth's surface, influencing their acceleration regardless of their momentary state of motion.
