It slows your speed down every time your feet touch the ground.
Sliding Friction
When things are rolling.
Yes. Friction is the resistance between an object and the surface in which it is. When pushing the coin, an opposite force is pushing it the other way, because the forcce you apply to the coin is greater it moves but that doesn´t mean there is no friction.
frictional force which is generated due to interlocking of minute roughness of slipper / shoes/foot with those of floor
There are plenty of friction occurring in a running car. Here are some examples:a) the different parts like the pistons, and the different gears and shafts in its main engine.b)The cars breaking system which uses its brake-pads and this discs breaks using friction to stop the car.c)The car moves forward or stop by means of friction between its tires and the road
The brakes apply force to the wheel, causing friction which stops it.
Air friction
track. anything that has to do with running. you use friction when running. but as for the 5 without use of friction then i have no idea
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.
when we run we push the ground backward it causes friction

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

Of course! Friction applies in gymnastics in TONS of ways.
Yes. Ideally, it's fluid friction.
