Ideal. Subby, the word is ideal.

You can never have a perfect soccer kick, because soccer is not hockey and thus sucks.

Hockey would be the most entertaining of North American sports if only they didn't feel obligated to have a fight all the time.

Actually it still is the most entertaining because it's up against rounders, netball and armoured rugby.

At least this thread will be nice and warm.

What subby meant to say is that after 90 minutes of preparation, you might score a goal.

We had to do a presentation at the end of the year on a "related topic" for my physics class in College. There were a lot of occupational / sports therapy type majors in my class; most every presentation was something along the lines of this article. How to take the ideal slapshot, the physics of soccer, of ballet, of gymnastics, etc. Is there something that was unknown about this? I mean obviously, it goes beyond your basic kinematics, but it doesn't look like anything unknown was worked out?

Did they also calculate the perfect flop formula?

With some assumptions. There's also accounting wind, deformation of the ball, curvature of the Earth, etc etc etc. The equation is hardly perfect.

machoprogrammer: Did they also calculate the perfect flop formula?


Yeah, it's a combination of speed (L), timing (a), pained expression (m) and duration of time on the ground (e). The formula for the perfect flop in soccer = (L*a/m)^e

You also need to assume the ball is a perfect sphere.

What type of kick and what direction do they want the ball to go?

I'm sure Pele showed us that there are a variety of kicks that can send the ball into the net.

To equate to hockey: wrist shot to the five hole? Seven hole? Top corner?

Maybe it would be better if they stopped the game every 10 seconds, paused for five minutes while they wander around aimlessly, zoom the camera onto old, fat men with big headphones and then grab each other's asses, all the while wearing shiny tights?

Also the angle of your fake hurt shin to the ground, as you clutch it (o). So its really:

((L*a/m)^e)-o

The players would probably like that, considering then their flops wouldn't be caught on camera

Why would you need a tape measure? The goalie's handling area is an 18 yard box. And many places have tidy rows of cut grass so you can estimate how far to go.

And the defenders have to be ten yards back from a free kick. Aim to the side of them and add spin to the ball.

The "bending ball" graphic... while it may pass the defenders on a curve, isn't it patently obvious to the goalie where its going to come in from give or take a few feet? And wouldn't that be easy to defend... for the goalie?

Isn't the point always to combine your skill *and* also take advantage of the fact that the you have a 50/50 chance of fooling the goalie and getting an easy score.

/Not a huge soccer fan, its fun, but I know nothing of the strategy at all.

Old news is old. I remember reading about this a few years ago.

The coolest part about this is that you are putting the ball on a spiral trajectory. In space the ball would actually come back around.

I think that Shunsuke Nakamura perfected it before they did.

FTFA: "ball's angular velocity (ω), it's velocity through the air (v), it's mass (m) and the distance travelled by the ball in the direction it was kicked (x)"

ITS, you farkin' morons.

At long last, someone has found a way to make soccer more boring

Have they figured out the formula for Los Locos to kick your balls into OUTER SPACE?
