Another idea that came up while flying to Florida was the principle of relative motion. When ever people are traveling they are usually only focused on their speed and not that of others. However, as i looked out of the window, I saw another plane in the open sky and it seemed that it was going much faster than us. However, knowing the principle of relative motion, i realized that we were most likely flying at similar speeds and it only seemed that the other place was flying fast because we were flying in different directions. Due to this, the relative speed of the other plane from my perspective would be our speed plus the speed of the other plane. However, if we happened to be flying in the same direction. the relative speed of the other plane would be the absolute value of my speed subtracted from their speed. So next time you travel know that things in your surroundings are not moving as fast as they seem to be.
