Does the acceleration of a projectile ever go to zero?
Question
Does the acceleration of a projectile ever go to zero?
Solution
No, the acceleration of a projectile does not go to zero during its flight. This is because the force of gravity is constantly acting on it. In the absence of air resistance, the only force acting on a projectile in flight is the force of gravity, which pulls it downward. This force causes the projectile to accelerate downward throughout its flight. This acceleration due to gravity is approximately 9.8 m/s² on the surface of the Earth. Even at the peak of its trajectory, the acceleration of the projectile is not zero; it is still 9.8 m/s² downward.
