In the last experiment, when a sand bag and coffee filter were released separately from the same height, the sand bag reached ground earlier because, the sand bag is heavier than the coffee filter. the resistive force of air slows down the coffee filter more than the sand bag. the air is thinner near the sand bag than near the coffee filter.

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.
