Discover it yourself: map-based motion at any speed

This page is one step in a personal journey to discover 20th century methods for describing motion.

Excellent choice, according to our sources! You can arrive at 141 meters experimentally, by measuring the distance in millimeters on your screen between red and orange clocks, dividing by the distance in millimeters between orange and purple clocks, and multiplying by 100 meters. Or you can follow Pythagoras' advice and calculate the square root of the sum of the squares of the distances in x and y between red and orange clocks. In other words, the distance is the square root of (100 meters in x squared plus 100 meters in y squared), or the square root of (10000 square meters plus 10000 square meters), or the square root of (20000 square meters), which rounds off to 141 meters after calculating the root.

You seem comfortable with the way that the distance between events depends on your frame-of-motion. Click HERE for the next challenge, where we begin applying our modern awareness that time increments depend on frame-of-motion as well.
