What is required to cause acceleration?
Answer (3)
constant force. Basicly in no gravity you have to keep puching smth for it to accelerate and once you stop it just would remain at the same speed. On earth the fact that something is falling faster and faster means it keeps beeing constantly pulled by gravity so the same principle applies
Acceleration means any change in speed or direction of motion. Any of those requires force.
Acceleration occurs when a net force acts on an object, as per Newton's Second Law. This can result from applied forces, gravity, or changes in direction. Gravity, for example, provides a constant acceleration of approximately 9.8 m/s² for falling objects.
