Pushing a heavy rock
Bad friction is when you dont wear socks so the shoe will rub against your foot ti cause blisters and pain. Peace out!
No friction is not always bad. In fact consider an example of running on wet floor. If there is too little friction it might cause you to slip and slide.
bad friction is when 2 things rub together .
You walk and that is the example of friction
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.
Blue cheese is a non-example of friction.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
Some machines need friction to operate. Brakes, grinders, traction wheels, and others all rely on friction to work. In other cases, friction is bad. electric and fuel-fired powerplants for example, are all designed so as to minimize friction. That's why the lubricant industry exists!
An example of fluid friction is the air resistance felt by an airplane.
Sliding your hands together is an example of sliding friction.
