Why do the predictions for a bouncing ball's trajectory diverge between general relativity and Newtonian gravity? This question was originally answered on Quora by Paul Mainwood.

If that were all that happened, the ball would follow the parabolic trajectory that all of us studied in high school physics: up, forward and down. But there’s much more to it than that.

A new model accurately predicts the movement of elite athletes to catch the ball in parabolic flight. ScienceDaily . Retrieved June 11, 2025 from www.sciencedaily.com / releases / 2025 / 02 ...
