When a body just starts to move, the friction that is present is static friction. This friction occurs between surfaces that are in contact but not moving relative to each other, resisting the initiation of motion. Once the body overcomes this static friction, it transitions to kinetic friction as it continues to move.

Friction between the tires and the road helps transfer the force you apply to the car, allowing it to move forward. Without friction, the tires would just spin in place and the car wouldn't move.
Yes, friction is necessary for walking as it provides the necessary traction between your feet and the ground to push your body forward. Walking on a surface with low friction, such as ice, can make it difficult to walk without slipping.
It had better be! Otherwise, nothing could ever start sliding ... as soon as yourpull on the string becomes strong enough for the object to break free of thestatic friction and begin to slide, the force of kinetic friction would take over,and it would suddenly be even stronger!
FIRST OF UNDERSTAND WHAT IS FRICTION. FRICTION IS NOTHING BUT A FORCE THAT OPPOSES THE MOTION OF A BODY .THE ANSWER FOR THIS Qn. CAN BE EXPLAINED BY A SIMPLE EXPERIMENT!!!. CONSIDER A RECTANGULAR BODY THAT SITUATED ON ONE SIDE OF A SEESAW, NOW RISE THE OTHER SIDE OF SEESAW; YOU CAN SEE THAT THE BODY WILL MOVES ONLY AFTER A PARTICULAR HEIGHT REACHED. THIS IS DUE TO THE SELF ADJUSTING PROPERTY OF FRICTION!! .THAT IS WHEN YOU RISE THE SEESAW THE GRAVITATIONAL FORCE & MASS OF BODY CAUSE THE BODY TO TEND MOVE TOWARDS DOWN. AS YOU RISE MORE THE FORCE WILL INCREASES ALSO. BUT THE FRICTIONAL FORCE ALSO INCREASES WITH RESPECT TO THE DOWN WARDED FORCE.THAT IS THE FRICTIONAL FORCE SELF ADJUSTING!!!!. BEYOND THE FRICTIONAL LIMIT BODY BREAK FRICTION AND MOVE TO DOWN..
Energy is always conserved. When friction is present, the energy usually just turns into heat.
Think of a car, friction causes air resistance on the car and results in lower gas mileage, but without friction, the tires would just spin in place and the car would not go anywhere.

Friction is a force, of resistance, that takes place when two or more objects make contact and when there is movement with one another. Friction keeps your feet on the ground and prevents you from slipping. Fricition is just like gravity.

Friction was not invented just discovered
The use of friction is a science question, specifically a Physics question, not really a History and Politics question, unless you mean that friction is necessary in conversation, in order to be understood -- that is a profound question, but I doubt that you mean that, by your friction question. Assuming that you want a science answer: Friction is necessary, in order for you to have something to push against. You need that friction in order to place your foot down in one place, long enough for you to push off to someplace else. If there were no friction, you would just slide all over the place, and get nowhere, like sliding on ice. If you ever tried to get your footing, to stand up, while getting up from icy ground, ground that's covered with ice, then you have experienced what I'm talking about. The same principle applies to cars and tires: the tires have to be at least a little bit sticky, in order for the car to have enough traction, for the engine to get the car moving. Otherwise, you just spin your wheels.
When the wheels of a car turn, friction causes the wheels to push back on the road, which in turn causes the road to push the car forward. Without friction the wheels would just spin in place. You can sometimes see this occur on icy roads, where there is very little friction.
To start a fire using just sticks, one can use a friction-based method such as the bow drill or hand drill technique. This involves creating friction between a wooden spindle and a fire board to generate heat and create an ember, which can then be used to ignite tinder and start a fire. It requires practice, patience, and proper technique to successfully start a fire using this method.
Actually the good effect of friction is: if you drive a car you can make it stop, friction makes it stop. But the bad effect is: friction wears out machines so you can replace it. Hope it helps! :) Also with no friction the tires would just spin and go no place, and steering would be a problem.
As we know charges can neither be created nor be destroyed, they just transfer for one place to another.For eg. :- when we say that a body is negatively charged,then that doesn't mean the negative charge was created in the body, but it means that the charge is transferred from somewhere else. Usually the negatively charged particles escape into the atmosphere from the body when friction force is applied.
no, friction just changes the motion of an object.
