AI Thread Summary
The discussion explores the hypothetical technology needed for a cricket ball to stop and hover mid-air after being bowled. Key considerations include the need for a mechanism to counteract lift forces and gravity, while also addressing the conservation of momentum, which limits internal mechanisms for prolonged hovering. The idea of using gyroscopes is mentioned, but it is noted that without wind, aerodynamics cannot contribute to the effect. Suggestions like equipping the ball with propellers are dismissed as not aligning with the original concept. Overall, achieving such hovering with a conventional cricket ball in standard conditions appears unfeasible.

Just had a dream about someone that bowled a cricket ball (spin delivery) and after it bounced when it got to about a meter in height it just stopped dead in the air and hovered. What technology inside of the ball would be needed so that lift force was countered so that it would stop vertically and then another force against the gravitational to keep it in the air. Also is there anyway the velocity the bowler had given to the ball could just be stopped dead somehow.
Was thinking something to do with gyroscopes

Conservation of momentum rules out all internal mechanisms (if you want to stop it for longer than a few milliseconds). If the ball stops and it is not windy, you also rule out aerodynamics. I don't see a way to make that happen with a regular ball in a usual setup. Strong winds in the right directions can make the ball fly in nearly arbitrary patterns.

You could equip your ball with propellers and make it a small helicopter, but I guess that's not what you want.
 
thank you for your reply
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
