When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall to the ground at an increasing speed the longer the object falls to the ground. The force of gravity acts on objects in a direction that is perpendicular to the level ground.
The force is not affected by lateral movement and simply pulls the object down at the same speed as if it were stationary.
