Hello, I have come up with 3 physics question on badminton to improve my backhand clear and attacking lift. 1. Does a good smash have a high spinning rate, low or no spinning? A good smash = fundamental smash pose used(to endure your wrist, elbow, and shoulder) + high average speed generated 2. Will a spining (revolution) shuttlecock drop shorter or farther in horizontal distance than a no-spinning shuttlecock? One of coaching vids said spin will cause a shuttlecock to travel farther, but I heard a spinning golf ball cause to lift and to fall short in horizontal distance. 3. Will Smashing a spinning shuttlecock result a faster average speed of shuttlecock? Assume that smash cause a shuttlecock to stop spinning. (I am not sure that that assumption is realistick...)- this question is related to question no.1. I am not here to exam you, but just want to know physics behind badminton. Thank you for your time.
