During projectile motion (neglecting air resistance), the acceleration of the projectile is:

Answer: Constant and downward.

A Variable in magnitude
B Zero at the top point
C Constant and downward
D Horizontal and constant

Correct answer: C. Constant and downward

Explanation: The only force is gravity, so the acceleration is constant at g and directed vertically downward throughout the flight, even at the top.

Projectile trajectories launched at 15, 30, 45, 60, 75 and 90 degrees at the same speed, each annotated with range R, maximum height H and time of flight T, with coloured dots marking equal time intervals

Projectiles at equal speed: range is maximum at 45°, and complementary angles (30° and 60°) share the same range. Image: Cmglee, CC BY-SA 3.0, via Wikimedia Commons.
