If an object is moving on the same surface the friction is the same throughout. However, more friction is caused by a rougher surface and less friction is caused by smoother surfaces.
The mass affects the efficiency of an object. It adds more weight, which causes more friction. More friction=less efficiency
Friction causes object in motion to slow down. As friction increases, it takes more and more energy for an object to keep its inertia (momentum) and it begins to slow down.
the main causes of friction are molecular adhesion,surface roughness,and the plowing effect.
friction
Friction can be a friend when walking and when driving a car. For example, walking or driving on ice can be very risky due to the lack of friction. Friction can be a foe when it causes more work to have to be done or excess heating. Friction is responsible for our getting blisters on our hands or feet.

Small vaginas because that causes more friction.

heat causes pressure, pressure causes friction, friction causes spark, spark causes KABOOM! all in a split second

where is friction used in wrestling
Friction is not useful when ever we do not want it. Examples would be when two materials are rubbing against one another. The friction of ropes in pulleys eventually causes wear on both; friction of shoes or straps against the body causes blisters; friction airplanes travelling through the air - friction causes the plane to get hot; the moving parts of an engine get hot from friction...
There is no friction IN static electricity. However static electricity can be caused BY friction.
