Without friction, the players would have trouble moving, as friction between their feet and the ground is part of what allows a person to walk or run. It would also be more difficult to make the ball start moving, or effectively catch it as friction helps grip the ball. It would also be more difficult to stop opposing players as friction between a tackler and the person being tackled is a large part of what allows the tackle to happen in many cases.
Without friction, feet would simply slide along the ground rather then gripping it to propel a player forward or stop him, and the ball would be so slippery it would be nearly impossible to hold onto without completely cradling it.
Whenever a player wants to move across the field, or hold on to the ball.
your mom frictioned me last night!
Static
coefficient of friction = force required to move it / mass 0.8 = f / 300 0.8 * 300 = f 240(slugs) = f
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
for lifting the object there is no role of friction,but of air friction.since no info,. is given about it so air friction = 0.thereby for lifting we have mg = mass * 9.8 (the wight of the object). and for sliding we have 0.3*mg . therefore 0.7mg of more force is required to lift it.
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
Friction is essential for Walking and other movement. So obviously it is of paramount importance in football. Without friction, A player can't grip the ball, the ground pr other players. Running, which is the base of football, doesnt exist without friction. Hence, no friction = no football.
first you ejaculate onto the football, rub it around in your hands a bit and slide it across a smooth floor and WA LA you have sliding friction on a football XD
first they are called cleats not boots and they dont have friction.
