Friction

Projectile Motion
Friction Magnus Effect Bibliography
As the ball is kicked across the surface of
the field or through the air there is always a force acting in
the opposite direction of motion. If the ball is on the ground
this opposing force is called the frictional force, if the ball
is in the air it is called drag. These forces are what causes
the ball to slow down or as it moves.
Friction is caused when
two surfaces are in contact with one another and drag which is
also called air friction is caused whenever an object moves
through the air or a fluid. In soccer friction is something
the players have to overcome to make the ball move along the
ground and through the air. It is also used to curve the ball
along the ground using the spin of the ball and the frictional
forces opposing that spinning. Friction also requires that the
player kicks the ball with more force in order to overcome the
friction forces acting against it and increase its
acceleration.
