WHAT I LOVE,LOVE,LOVE

UNBALANCED FORCE/NET FORCE

• When you kick a soccer ball to the the goal the force is unbalanced.
• I know this because the ball is experiencing motion across the ground and
• because two forces are opposing and one has more newtons.
• If I kick a soccer ball with 50 newtons of force and the rolling friction
• is 10 newtons than I will have hit the ball with a net force of 40 newtons.

ROLLING FRICTION

• When you kick a socer ball it rolls across the
• field until the rolling friction or another force stops it.
• Rolling friction is occuring between the ball and the grass
• it's rolling on. This affects the motion of the ball by slowing it
• down unless another force keeps it going.

SLIDING FRICTION

• Sliding friction in soccer can occur when the goaly
• (or a player) dives for the ball.
• The sliding friction is occurring between the player and the ground.
• The sliding friction is affecting his motion by quickly slowing him down.

FLUID FRICTION

• When some one kicks the soccer ball through the air
• It is experiancing fluid friction.
• I know that this an example of fluid friction because the air
• Is affecting the balls motion by slowing the ball down midair.

INERTIA

• This picture is an example of inertia because the sliding player has a 
• tendency to keep going. I know this is an example of inertia because when 
• you slide you are using lots of force in your motion and the more force you
• have in your motion the harder it is to stop. Inertia is the tendency of
• an object to resist its change in motion so this is an example of inertia.

Balanced Force

• In soccer a balanced force can occur when the soccer ball roles to a
• stop and does not move. I know this is a balanced force because the
• ball is not experiencing motion with the reference point of the ground.
• The ball is pushing with 0 newtons and no force is acting on it (so 0 N. of
• friction) so it is a balanced force because the opposing forces are equal.
