Newton's first law states that, simply, an object in motion will stay in motion unless acted upon by an unbalanced force. It also gives the idea that an object that is at rest will stay at rest unless acted upon by an unbalanced force. Friction mostly has to do with the first part of Newton's first law.
The unbalanced force can be practically anything, like a shoe or tree. If there isn't anything that is going to counteract with the moving object, it will still stop. Why? Friction. It counts as an unbalanced force because it interferes with the motion of the object and in addition to that, it moves in the opposite direction of the moving object.

∙ 11y agoThe first law says that if no force acts on a mass its velocity is constant.
Friction would, of result in a force on the mass, so the law would not apply.
The first law actually defines frames of reference in which the remaining laws apply. Suppose you were sitting in an accelerating car watching this mass on which no force was acting. Its velocity would not appear to constant. So the first law in effect says this is not a good frame of reference for the purposes of Newtonian physics.
The good frames are called "Inertial Frames".
Because of gravity, its hard to find an "Inertial Frame" in nature. For short periods of time the inside of the International Space Station is a good choice. Here on earth you have to fudge things by treating gravity as a "force" even though you feel the force of gravity but aren't being accelerated!
But Einstein's Theory of General Relativity allows you to do physics in any frame of reference (from your accelerating car, for example, or on a roundabout - in General Relativity, centrifugal force (the force that pulls you outwards on a roundabout) is as real as gravity - there is none of this nonsense about "real" versus "fictitous"
forces.

∙ 11y agoThat's because Newton's First Law basically considers the case that no forces act on an object, or that the net force is zero. With friction, there is always a force, and this force is quite often unbalanced.

Does a ball need friction to roll?
sure a ball needs friction to roll. the logic behind this being, that the friction which generally retards a body's motion plays differently in this case, it acts tangentially in backward direction at the point of its contact with the rolling surface, so in this way , it generates a rolling motion
What is the role that friction plays in conservation of energy?
It makes potential and kinetic energy
What are the application of friction in vehicle?
Friction plays a very important and crucial part in our day to day life.Thanks to friction as the friction between the roads and the tyre of the car enable us to control the motion / speed and thus the car is prevented from an accdent.
What role does friction play in rock climbing?
It plays a very important role. It allows you to climb
How does friction affect basketball?
Friction affects Basketball in many ways. For starters, a player wouldn't be able to stop or run because of the lack relative motion on the surface of an object. Friction is necessary for the sport of basketball.

What friction is used while driving?
1) Friction of the tires on the road 2) Friction in the clutch 3) Friction in the brakes 4) Friction of driver against controls and seat Friction of air also plays a part in resisting motion; this can be used to improve road holding when we deflect it into a down force, hence the spoilers on F1 cars, for example
What role friction plays in hockey?
Because friction is a force acting against the forward motion of the puck, friction is going to play a role in slowing down the puck as it glides across the ice. The friction is not going to be great enough to stop it instantly, but if not touched by another stick for some time it will come to a stop.
If a 1-N force accelerates a 1-kg mass at 1 meter per second squared in a zero-gravity and zero-friction environment how do you calculate its motion in the presence of gravity and friction?
Your ideal scenario describes the near-perfect vacuum and weightlessness of space. As you said, a one-kilogram mass will accelerate at one meter per second squared if a net force of one newton is applied to it. But you wish to know what happens under real-world conditions, such as the existence of friction (air resistance, rolling friction, and sliding friction) and gravity. If the motion is in the horizontal plane and at low speeds, air resistance is negligible. Friction between surfaces and rolling friction are significant, however, and will act against any force used to accelerate an object. Gravity plays a role in the consideration of friction, as well, inasmuch as the frictional force is proportional to the Normal Force, which is related to the object's weight.1 For motion in two directions, such as the path of a kicked ball or the trajectory of a bullet fired from a gun, air resistance plays a large role as does the acceleration of gravity. Friction and the effects of gravity play a major role in calculations involving the motion in the vertical direction, whereas the acceleration of gravity plays no role in the calculations of the motion in the horizontal direction.2Basically, keep in mind that weight is a force directed downward. When determining the net force acting on an object, its weight is just one of the forces acting on it. 1. For an object resting on a flat surface with zero incline, the Normal Force is equal and opposite to the object's weight (W = mg). The frictional force is calculated to be uN, where u (the Greek letter mu) is the coefficient of friction. The frictional force opposes the direction of motion. For objects on an inclined plane, the Normal force is equal to W*cos(theta), where theta is the angle of incline. 2. Weight is a force perpendicular (orthogonal) to horizontal motion and, hence, can have no effect upon it.
What are the negative effects of friction?
Friction createsheat when ittwo or more objects rub together. This also present in microwaves. Another effect of friction is that it slows down objects thathave friction applied with them.ADVANTAGES OF FRICTIONFriction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure Foothold.DISADVANTAGES OF FRICTIONDespite the fact that the friction is very important in our daily life, it also has some disadvantages like:1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy.2. Due to friction we have to exert more power in machines.3. It opposes the motion.4. Due to friction, noise is also produced in machines.5. Due to friction, engines of automobiles consume more fuel which is a money loss.
