AI Thread Summary
Understanding the mechanics of an efficient throwing motion in football involves both physics and human anatomy. Key factors include the position of the arms, body weight distribution, and the importance of a proper follow-through for accuracy. While many suggest keeping both hands on the ball and releasing it near the ear with an obtuse elbow, individual differences in body type and strength may affect optimal form. Foot and leg placement also play a crucial role, as lower body strength contributes significantly to throwing power. Overall, while there are foundational techniques, personal variations must be considered for maximum effectiveness.

So I am very interested in physics but cannot always grasp all the topics fully, so I decided I would get help with this from others. First, I play football and am more of a student of the game than athletic. So I was thinking about the way a person throws a football. Given the footballs shape a spiral is needed when throwing the ball along with a shift in were the weight of the body is in comparison to the arm movement. The part I cannot figure out though is the position of the arms while throwing and after throwing, where the more promininent position may be for maximum accuracy. Many people say for both hands to be on the ball and for the ball to be near the ear and released after it passes the head when the elbow is just obtuse. Also would holding the hand in place after the throw, or a follow through, really be that important for the throw? I feel that the follow through cuts down on the balls spiral. Anyone that can help thanks! And also thanks for reading this long question haha I enjoy using science to discover random things haha
 
Physics news on Phys.org
While there is of course physics involved I think there is even more human anatomy. I can't imagine that with different hand sizes and strengths, different overall arm lengths, different forearm lengths and muscle development there is a standard 'form' for all. But there may well be basics from which to start,

You should also note that foot and leg placement is also important; some pros can pass on the run, others can't, but I know the pros have some recommendations for foot placement and body orientation when trhowing.
 
Thanks for the help! But I personally feel that the difference in strength and body types of athletes would not make a difference, like how in basketball there's a perfect shot that few have perfected. Also the leg positioning definintly does help when throwing as most of a persons strength comes from the lower body, thanks for your input.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
