when you fall on your knee the friction from the court comes to your kne and your knee starts to sting same with any other body part
To the bowler, friction is a great aid in determining the spin and bounce of the ball. And to a fielder when returning the ball. To the batsman - not much.Similar comments apply to Baseball, Netball and Basketball etc.
you apply for it
Friction is applied, by making the surface of whatever you want to slide across it (the thing you want to apply friction to) is really rough. You can inscrease, and decrease the amount of friction acting on an object by changing the texture, material and smoothness of the surface. Smoother surfaces don't apply much friction to objects, and rougher surfaces apply a lot. An example of this, is Wellington Boots. They have rough underneaths, so you don't fall over - they apply a lot of friction.
it is very stupid and dumb
When things are rolling.
there is nothing called as principle of friction. friction is just a force which will act in the opposite direction of which you apply force.
In many ways
when your sliding to guard someone and running
Of course! Friction applies in gymnastics in TONS of ways.
To decrease the magnitude of friction, you can apply a lubricant between the surfaces in contact, use smoother materials to reduce surface roughness, or apply a force to counteract the friction force. Reducing the normal force between the surfaces can also decrease friction.
When you apply the brakes, you are experiencing kinetic friction between the brake pads and the brake rotors. This friction converts the kinetic energy of the moving vehicle into thermal energy, which helps slow down the vehicle.
