Document Summary

Stand still->ball move up and down for everyone. Moving->we see ball doing arc, she sees ball moving up and down. No clock -> know speed and distance t=d/v. Agree on the time but not the distance: trajectory of bean bag if you walk next to jackie-> looks same, time direction. Time runs more slowly in the reference frame of anyone moving relative to you. The faster the other reference frame is moving, the more slowly time passes within it. 2 spaceships, ones travelling past you: remember what perspective you being asked from. Time literally slows down for the person who is moving. My perspective-> leila s clock is itching slower than yours.
