Physics in soccer

In soccer, like so many other physical activities, there are countless examples of physics. Newton's 3rd Law is evident for as I kick the soccer ball, the force of my foot acts on the ball, while the ball is at the same time applying a force to my foot. This supports Newton's idea that with every action there is an equal and opposite reaction.

Free Fall is another physics- related component of soccer. When our goalie punts the ball one can examine the motion of the object as it travels up through the air to determine the initial velocity. When the ball has reached its peak, it has a velocity of zero. As the ball travels downwards, back to the ground, it is accelerating at a constant rate of 9.81 m/s^2. This information is accurate as long as the ball is left untouched. An object in free fall is always pulled by gravity at a constant rate of 9.81 m/s^2.
