AI Thread Summary
The discussion centers on the physics of soccer ball dynamics, particularly how various physical concepts apply when a ball is kicked. Key topics include the effects of velocity, projectile motion, and forces like drag and gravity on the ball's trajectory. The importance of translational and rotational kinetic energy, as well as linear and angular momentum, is debated in relation to the paper's focus. There is curiosity about the mechanics behind bending the ball during free kicks, especially in cases like the knuckleball, which lacks spin. Overall, the conversation emphasizes the need to balance complexity with clarity in the paper while exploring relevant physics concepts.

The physics involved in soccer?HELP PLS

I am writing an extra credit paper which is +10 pts added to my final grade...I decided to do it on soccer. He wants use to pick a topic that involves physics and write a 4 pg paper...
This is my paper so far:
In the game of soccer many physical aspects occur as soon as a ball is kicked. From the moment when a soccer player’s cleat makes direct contact with the ball to the moment when the ball it hits the ground or is shot into a goal, many different physical concepts become involved. I will touch base on a few of these concepts: 1. the effects that velocity has on the ball 2. The path the ball takes after being kicked (projectile motion) 3. and some important forces acting on the ball while it is in the air. Examples would be drag, gravity, flow of air, aerodyamics, Magnus Effect...

I just need to know if I'm off at a good start? I haven't been on this forum since last summer and it was very helpful! Please respond!:smile:
 
Physics news on Phys.org
Seems reasonable.

The ball has translational as well as rotational kinetic energy, as well as linear and angular momentum, depending on how it is kicked.

Then there is the air resistance and ground resistance.

As a soccer (futbol) player, one can appreciate the physics invovled.

Knowing just how to meet the ball with one's foot or head is an art.
 
anymore suggestions or thoughts?

well is it necessary that I bring up translational/rotational kinetic energy, and linear and angular momentum or air resistance and ground resistance? I don't know how important these concepts are compared to what I am going to talk about in my paper. We can't go over 4 pgs so I was trying to keep it kinda simple...?
 
Maybe you could focus on one topic. I'm a bit curious how they can get the ball to bend so much on free kicks, i.e. around human walls. One would be tempted to say rotational kinetic energy, but if it is a knuckle ball (no spinning) how is it bending? This is true for baseball as well.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
