It is important in keeping objects; cars, humans animals, anything, from sliding around. Friction can cause heat as well, becasue when two objects rub together they form heat.
Work = Force x Distance Friction is a force usually operating in the opposite direction to the force being applied. Thus friction adds to the size of the force applied and work is increased.
I'm not sure.
yes it is, this refers to the force being created by the moving object (in perspectives-) a car which travels down the road has thrust in order to propel itself forward however there is also friction force with OPPOSES motion of the object, thus friction is regarded as a force, also support force (from the ground) or gravitational force is an equally right choice in terms of common forces. Therefore your statement/question in regards to friction being a force is true.
The force of friction, which is the normal force (weight) multiplied by the coefficient of friction (how rough the carpet is).
Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.
Static friction is not necessarily an applied force, but something that occurs when there is an applied force. Static friction occurs when there is no motion and there is a force being applied to an object on a surface.
Work = Force x Distance Friction is a force usually operating in the opposite direction to the force being applied. Thus friction adds to the size of the force applied and work is increased.

Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)

Newton's first law of motion categorizes any force affecting the motion as an external force. Friction being an external force, negates its presence as an integral force of a motion. Hence friction cannot be used to observe first law of motion.
Statical friction
friction is a natural force
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
