Because without it, you couldn't walk.
No, static friction and kinetic friction are separate forces that act in different situations. When an object is at rest, static friction opposes the applied force. When the object is in motion, kinetic friction opposes the motion. To find the total friction force, you would just consider the friction force relevant to the situation.
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.
when the friction is absent during the motion there may be a chance of skidding occurs. there should be some amount of friction during the motion of any body also there should not be too much friction as it decreases efficiency of the vehicle.
When planning for college, you should consider:
friction is a vigorous rubbing movement used when shampooing on the scalp areas
If it weren't for friction, a baseball would slide off of a bat when it should be hit.
We should drive slowly because water is a lubrian. A lubrian is a substance that lessens the friction of a substance. Friction helps in breaks but if there is no friction you would not be able to stop the car easily and would eventually be in danger. -Avi Shah-
Gravity is good. It keeps the cars down on the track, and the fans in their seats. Friction is bad. If there was no friction, then you could cut your engine when you hit 200 and just keep going. But friction robs your kinetic energy, so if you back off your engine, then your car slows down.
You should consider your fat tissues as your body fat.

The graph of force of friction vs total weight is typically linear, following the equation of force of friction = coefficient of friction * total weight. As total weight increases, the force of friction also increases proportionally. The slope of the graph represents the coefficient of friction.
Friction between bricks can help to distribute the load among the bricks, enhancing the stability of the structure. However, excessive friction can lead to cracking or shifting of the bricks under load, affecting the overall integrity of the structure. It is important to consider the appropriate level of friction in brick structures to ensure long-term stability.
