Projectile motion is a motion in which an object is thrown/launched into the air and has a distinct path which looks like a curve. The object goes up and slowly goes back down. In projectile motion gravity is has two different jobs. Horizontally gravity does not take into effect on the object. But gravity does effect the object vertically, changing its height while in the air.
Favorite soccer player, Mario Gotze, a Borussia Dormund midfielder in the German soccer league called Bundesliga, kicks the ball up into the air. The ball will soon be pushed down to the ground by gravity where Gotze can trap it and move, unfortunately, gravity is making the ball drop fast and since gravity doesn't effect the horizontal orientation of the ball, Gotze has to sprint to keep up with the ball and be there when the projected ball lands.

This graph is showing that the horizontal speed is constant staying at around 5.22 m/s the entire way. The speed did not change horizontally because gravity only effects the vertical motion of an object the the horizontal motion. This graph also shows the vertical speed of the ball. The ball increases speed as it gets higher and then decreases speed as its about to hit the ground.

In the video above, you will see how Mario Gotze along with his moves, shows projectile motion when he shoots and sometimes even when he passes, whenever he puts the ball in the air, projectile motion is present. Projectile motions are constantly happening in soccer and many other sports.
Above is a video we did, we kicked a soccer ball, showing projectile motion, the ball was projected into the air which eventually lands because gravity is affecting the ball vertically, gravity doesn't affect the ball horizontally so it will not slow down unfortunately. Next time we could try and analysis a baseball hit into the air, that would be really cool, and maybe even calculate where its supposed to land so someone can catch it.
