Law of Inertia
When a soccer ball is in motion, it will stay in motion (unless acted upon by an unbalanced force)
When a soccer ball is at rest, it will stay at rest (unless acted upon by an unbalanced force)
In soccer the unbalanced force is usually a player’s foot, however it could also be wind, gravity, or any moving object. A player uses his muscles to create enough force to kick the ball, since the ball would be a rest and remain at rest. However once the ball is in motion it will continue to move without any plan of stopping. The explanation behind this is the ball comes to a stop is because of the gravitational pull by the earth and friction.

Newton’s Second Law
F=ma
Force = mass X acceleration The acceleration of the ball depends on how hard the kick was divided by the mass of the ball
Newton’s second law states that “The change in velocity (acceleration) with which an object moves is directly proportional to the magnitude of the force applied to the object and inversely proportional to the mass of the object.” In soccer the amount of force (F) determines the acceleration of the ball (a). If the mass of the ball (m) is low, the force necessary is low (F). This means if the mass (m) of the ball is high, it will take more force (F) to accelerate (a) it. This is important for any soccer player because if the player wanted to kick the ball faster he would need to kick it with more force, and the exact opposite for kicking the ball slower.

Newton’s Third Law
For every action, there is an equal and opposite reaction
When soccer ball is kicked, the kicker experience the same amount of force the ball experiences
Foot->Ball Ball->foot
This simply means if a player kicks a ball, the player will experience an equal and opposite force upon his foot. The reason that it is not noticeable is because the muscles in the foot have a greater mass and inertia so it has resistance.

Friction on the ball
Friction is what causes the ball to stop moving on a grass field. Grass has a higher co-efficient of friction then turf. Friction occurs because of the forces between the grass and the skin of the soccer ball rubbing against each other. This turns kinetic energy into heat.
Technically speaking if you kick a ball hard enough it could catch on fire.

Drag on the ball
Drag occurs when the ball is kicked of the ground and is in mid air. The ball pushes the air and the air pushes the ball, which causes the ball to slow down. Drag on the ball is the reason a soccer ball doesn't have a perfect parabola. However if there is spin on the ball it lowers the amount of drag on the ball.
Center of Gravity
Since the soccer ball is a sphere, its center of gravity is in the center. This means its trajectory is easily expected, unlike a football where it’s shaped like a cone.
