The textbooks say that the maximum range for projectile motion (with no air resistance ... Projectile Motion – no air resistance Using the main ideas above and the kinematic equations (for constant acceleration), the following should be true: Note ...
What does physics reveal about the sizes of sports fields?
In their study, the researchers analyzed 13 sports, each involving a ball or other projectile (for example, a shuttlecock or "birdie" in badminton). Each ball has a different range, defined as the maximum distance that the ball can travel in one shot.
