If an object is thrown downward from a tall cliff, its acceleration while falling (in the absence of air resistance)will be A)less than 10 m/s². B)10 m/s². C)greater than 10 m/s². This is evident from the fact that D)gravitational force depends upon the state of motion of an object. E)each successive second the speed of the object increases by an additional 10 m/s. F)the object was not simply dropped but thrown, therefore having an initial acceleration of fall greater than zero.

The acceleration due to gravity is constant at 10 m/s^2 near the Earth's surface, regardless of the object's initial motion (B). This constant acceleration means that the speed of the object increases by 10 m/s every second (E), not depending on whether it was dropped or thrown.
