4.2. high speed problems

The traveler-kinematic approach works regardless of speed. As a result, the short introduction above opens the door to calculations involving velocity and acceleration at super as well as at sub relativistic speeds i.e. for proper velocities (and momenta per unit mass) well above or well below 1 lightyear per traveler year. 

Some sample problems involving high speeds are provided on the subpages linked below. They cover topics, in order of increasing required sophistication, like:

• colliders versus accelerators

• anyspeed road safety

• single-frame time-dilation

• accelerated round-trips

• addition of 3-vector velocities

  • acceleration-related aging.

These problems should be possible for students to work with only the mathematics background needed for an introductory physics course.
