A.5.4 (HL)—Galilean velocity addition Topic Practice
Practise adding and subtracting velocities in Galilean relativity to find relative speed, closing speed, and signal travel time.
How this is tested
- add or subtract signed velocities to find one object's speed in another frame
- set up cDelta t = d + vDelta t to find when a light signal reaches a moving spaceship
- use the closing speed from a simple velocity table before calculating meeting time
