Suppose you drop an object from an airplane traveling at constant velocity, and further suppose that air resistance doesn’t affect the falling object. What will be its falling path as observed by someone at rest on the ground, not directly below but off to the side where there’s a clear view? What will be the falling path as observed by you looking downward from the airplane? Where will the object strike the ground, relative to you in the airplane? Where will it strike in the more realistic case in which air resistance does affect the fall?

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
