Inertia
Newtons Second Law Of Motion
Newtons first law of motion:
There is no motion in the ball untill
it is being kicked and that is the force that is putting the ball into motion.
Motion
When a soccer ball is kicked the result is it being put into motion because of the force put on it
The shooters need to consider the inertial tendency of the ball to keep going straight when making an attempt around the defenders. So some spin on the ball, to cause it to curve away from the straight line and a defender, is necessary. The spin applies a sideways net force to the soccer ball. And to get the ball moving at all requires a good swift kick, to overcome its tendency to just sit there on the pitch.
An example would be if a ball has a lot of mass it will require more force to move. If the ball has little mass, it will require little force. In soccer this is important to know because a lot of times you are having to control the speed of the ball.

Speed
Newtons Third Law Of Motion
The amount of speed within the contact of the foot and the ball is going to change how far the ball goes. the faster you make contact the farther it will go. the slower you make contact the less far it will go.
This law states that "for every reaction , there is and equal and opposite reaction.” This means that if you kick the soccer ball, it will kick back at you just as hard. People don’t realize it because your leg doesn’t seem to move, but it is because your leg has more mass, meaning it has more inertia, which is the resistance to move.

Friction
Unbalanced And Balanced Forces
When a soccer ball is kicked along the grass surface, there is always a force parallel, but opposite of the ball. Friction is caused when two opposing surfaces make contact with each other. In this case, it is the ball and grass. However, friction can also happen when the ball is in the air. Because air is matter, friction is always present. Friction is the reason why the soccer ball always slows down.
Action/Reaction
A balanced force would be the ball not moving, and an unbalanced force would be the ball moving
Acceleration
The action would be kicking the soccer ball and in this situation the reaction would be the ball moving.
The soccer ball accelerates when you kick the ball.
*The average acceleration when kicking a soccer a ball is about 8 meters per sec.
