To gain an idea of the kick force generated by a professional soccer player during a kick we can use the impulse equation: F avg Δt = m b ΔV b, where F avg is the average kick force during the impact between ball and foot, Δt is the time duration of the impact, and ΔV b is the change in velocity of the ball during impact.
On the figure, we see the trajectory of the soccer ball as it moves from right to left. The radius of curvature R of the flight path depends on the velocity V of the kick and the acceleration a produced by the side force. R = V^2 / a

Speed (or Velocity) is calculated in the equation V= ∆d/∆t where ∆d represents distance, ∆t represents time, and V represents velocity. Therefore the velocity of the ball I kicked was 3 m/s.

Soccer is the most popular sport in the world. Soccer players all work very hard to keep in shape, and to improve their kick. Most of them don’t know that there is a scientifically correct way of going about doing this. I researched the physics of soccer and found some very interesting facts that all soccer players would do well to learn.
Air resistance slows the ball down in flight making is velocity in the x direction decrease as it travel through the air. As with any projectile, a soccer ball flying through the air follows the equations for projectile motion below and follows a similar path to that shown in the figure.
So far, there has been minimal mathematical research on soccer kicks, although there have been numerous studies on the physics of soccer and how the ball curves. Investigation: First, I created a model of the playing field in Geometry Expressions. The field has dimensions of 120 yards by 75 yards, the goal
