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.

Describe a means of transportation and a point-to-point travel route with which you are familiar. Use this route to explain the difference between and the meaning of the following terms: distance, displacement, speed, velocity, and acceleration. Do not use a path with zero displacements; for example from home to work and back home. Identify those quantities which are vectors, and which are scalars. Give magnitudes and direction from your example route as appropriate.
