WHAT I LOVE,LOVE,LOVE IS FOOTBALL

SLIDING FRICTION

• When a Quarterback slides to get a first down.
• This stops the Quarterbacks movement.

ROLLING FRICTION

• When the ball is fumbled.
• Makes the ball roll away.

FLUID FRICTION

• Running the football.
• The air slows the player down.

BALANCED FORCES

• Two people equal size go up against eachother.
• They don't move because they are equal forces.

UNBALANCED FORCES

• A little guy goes up against a bigger guy.
• The bigger guy has more force than the little guy.

INERTIA

• The pushing sled.
• It has a larger mass so it takes 5 players.

MOTION/REFERENCE POINT

• The football is in motion compaered to the feild goal.

2 lineman go up against each other. Each is pushing opposite directions with a amount of 200 Newtons. The net force is 0.
