The English got the formula of the ideal free kick

Riva Kesli verifies the formula

It’s no secret that the absolute majority of well-known (and little-known) football players do not have special achievements in the field of physics and mathematics, just as there are no football stars among outstanding physicists and mathematicians. And meanwhile, they could be useful to each other.

Physics students at the University of Leicester (UK), figuring out the radius of the ball, the distance to the gate and the density of air, derived the exact formula of the ideal free-kick guaranteeing a 100% goal.

Formula ideal free-kick

They decided to test their theory in practice during the traditional Big Bang fair, in which young British scientists participate. Riva Kesli, a member of England’s youth national football team, tested and tested the “perfect” kick on the ball. As the authors of the formula, knowing the size of the ball, the density of air and the distance to the gate, the player can correctly beat, each time scoring a goal.

The formula reflects the behavior of the ball in flight, when it is affected by the so-called Magnus effect. A person who is ignorant in mathematics, this formula may seem complicated. But in fact it is just a mathematical expression of what class players do all the time before they break free, a penalty or a penalty.

For example, a player preparing to break a free kick, becomes 15 meters from the ball. To ensure that he accurately flew into the goal, he needs to give a speed of 35 m / s, an angular velocity of 10 r / s, which will force the ball to fly along a 5-meter arc.
