Ever heard of Gravity?
You know, the force discovered by Isaac Newton? Well just incase i'll give you some insight so you can put it in FIFA 2010. Every planetary body (including the Earth) is surrounded by its own gravitational field, which exerts an attractive force on all objects. Assuming a spherically symmetrical planet (a reasonable approximation), the strength of this field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body. The strength of the gravitational field is numerically equal to the acceleration of objects under its influence, and its value at the Earth's surface, denoted g, is approximately expressed below as the standard average. g = 9.8 m/s2 = 32.2 ft/s2 This means that, ignoring air resistance, an object falling freely near the earth's surface increases its velocity with 9.8 m/s (32.2 ft/s or 22 mph) for each second of its descent. Thus, an object starting from rest will attain a velocity of 9.8 m/s (32.2 ft/s) after one second, 19.6 m/s (64.4 ft/s) after two seconds, and so on, adding 9.8 m/s (32.2 ft/s) to each resulting velocity. Also, again ignoring air resistance, any and all objects, when dropped from the same height, will hit the ground at the same time. According to Newtons 3rd Law, the Earth itself experiences an equal and opposite force to that acting on the falling object, meaning that the Earth also accelerates towards the object (until the object hits the earth, then the Law of Conservation Energy states that it will move back with the same acceleration with which it initially moved forward, canceling out the two forces of gravity.). However, because the mass of the Earth is huge, the acceleration of the Earth by this same force is negligible, when measured relative to the system's centre of mass.. So that means for instance when we shoot the from more than 20 yards.... yes the ball will come back down!! |

That calculation doesnt factor in object velocity or change in shape with an object like a football that is not solid and has a very low mass compared to its surface area.
It also doesnt account for aerodynamic spin or wind. All that equation means is that there is a force that is constatly acting upon the body. That force is over comeable (this is why we have space shuttles etc) but given the power and speed that a modern football can be hit with and achieve it will over come the initial pull and only when it loses enegry will it feel the full force of gravity. If this were not true then we could only need the goals to e about a foot and a half high and I would only shoot from at most about 3ft............. |

The fact is if you take a shot from outside the box tapping the shoot button very quick with minimal power 80% of the time it flies over the bar. Whats the point in having a power bar when it doesnt matter how little power you use it goes sky high. Another thing, Just do a shot from say the half way line, maybe from kick-off watch the ball go to about 2-3 meters off the ground then maintain that height for 40 yards then suddenly start rocketing toward the sky. Its stupid. |

you playing the demo or something???
The ball physics seem perfect to me. BTW 80% is A LOT of power. Go outside and kick a ball with the inside of your foot about 80% near the bottom of the ball and see how high you can get it

yup... i found that shot power makes a HUGH difference. my BaP guy has 99 shot power and they stay down much better...
i find people like rooney rarely gets the ball on target from long range shots - even with assisted - yet everyone thinks he can score from anywhere... a slight tap is all you can do but then there is no power...

You add velocity to a given object say a football and depending on the velocity and aerodynamics of said object you will see not only does the object over come gravity it also will rise, dip and swerve. As I said the ball physics are pretty good in fifa, havent played pro evo but the only differences will be in spin/dip/rise factor and this will be down to the arbitrary weight at which the ball is given and the way in which velocity is applied (how its kicked, the angle of the kick, the spin amount) etc. |

I will go to the arena and upload a video this afternoon if i get 2 mins away from work. The physics are fine in this game. Have you not heard the saying "row Z" when RL players take shots. If you only watch MOTD then you wont see all the high wide and hansome shots! Also do a youtube for cross bar challenge (soccer am do it) and you will see some wildly varying shots and swerve etc |

In my follow up post I said ok, I read your post wrong why the attitude? Because I dont agree with you? Or is it that gravity is only a finite force that when velocity is applied to it the affect of gravity is lessened? |

Im talking about in the intensity of a game when you're passing the ball around fast outside the box waiting for your moment and then bam! you see an opening in the defence take a 25 yard shot by tapping shoot so fast ur power bar goes 1/5 of the way up max then you see it fly 30 foot in the air.

What do you mean by that because lets say you are playing right to left then you aim the analogue stick left when you shoot, maybe slightly towards a corner so it would be north-west or southwest but if you aimed the analogue down or up you would be kicking the ball out for a throw.

All of you guys trying to tease the guy are not worth coming to this forum.All he is saying is that the ball floats too much and with a little tap,it moves too high.Simply put,the ball physics are not good enough for a 21st century football game.Now y'all taking about analog stick and ****.you guys are able to do it cause you have exploited the game and have found a way to go about it.I bet you don't enjoy the game as much as you want to cause the realism of shooting the ball into the net and enjoying your victory sactisfactorily ain't there.
I know some idiot would reply in the way idiots should.If not then well done and thanks for listening |
