This physics application for Windows, Relativity 1, shows the time dilation, the mass expansion, and the length contraction when one student in a hypothetical journey travels in space at speeds near the speed of light. The application will assume the following information for one student:

Mass of the student = 60 kg

Age of the student = 18 years

Length of the spacecraft = 150 m

Year the student left planet Earth = 2,022

The students will return to Earth after 20 years, as indicated by a

clock in the spacecraft.

By just pressing each time the space bar, starting at 0.1c and increasing gradually all the way to 0.999999998c, the computer will show:

Mass of the student while traveling in spacecraft

Length of the spacecraft while moving in space

Age of the student when returning to Earth

Years passed on planet Earth since the student left

Current year in Planet Earth when the student returned

Again, this physics application is for computers using Windows 10 or newer.
