Which of the three (postion, speed, acceleration) is caused by gravity?
North Tonawanda,New York,USA
For a body affected only by gravitational forces its acceleration is directly proportional to the gravitational force divided by its mass. Now, given an initial position and velocity one can then calculate the subsequent positions and velocities at later times by integrating the acceleration.
So in a sense, gravity directly causes acceleration and indirectly affects position and speed.
