What is the function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
What is needed to determine whether an object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
What is the difference between Kinetic And Kinematic?
Kinetics is a concept only involved with the movement of objects, while dynamics focuses on the forces and their effects. In certain point of view, we can say kinetics only deals with the motions of objects, and dynamics with the reason why and how they moves.

Why is friction needed in the brakes?
Newton's First Law of Motion states: "An object in motion, remains in motion, unless acted upon by an outside force". Friction is an additional outside force that stops the motion of a vehicle faster. Without friction, the vehicle would never stop until it crashed into something.
What factors that affect motion?
An object's motion is affected by the initial speed and acceleration and the forces that interact with it, the most important being: Gravity - that is affected by the gravitational constant g - which is affected by altitude; Air friction - that depends on the speed of the object and it's volume and air density; Surface friction - depends on the size of the surface of contact, the force that the object exerts on the surface, the surface and the object's coefficient of friction; All the above forces are proportional to the mass of the object.
Why is it difficult to pull a rug from below a person sitting on it?
The coefficient of friction between the person and the rug is high and a lot of force is needed to overcome that.
A sled of mass 53.0 kg is pulled along flat snow-covered ground The static friction coefficient is 0.30 and the kinetic friction coefficient is 0.10 a What force will be needed to start the sled movin?
Ignore the kinetic friction coefficient, that is only in the problem to trick you. If the force pulling the sled is parallel to the ground, then the problem should be pretty easy. Acceleration due to gravity = 9.8 m/s^2
What type of friction is the frictional force needed to start on object at rest into motion?
Static
How friction affects motion?
Friction is a very helpful thing and with out it you couldn't move, speed up, slow down, change direction, bend, or twist. Without friction nothing would ever happen. Friction can oppose motion or it can make it difficult for an object to move across a surface. Friction both helps an hinders every thing we do.the object would not move without frictionThe friction acts in the opposite direction to that of direction of motion.So friction slows the object and if no external force is applied the object will come to stop.Friction is a force that opposes the direction of motion between two materials. It is parallel to the surface your object is touching. Friction depends on the coefficient of friction and the normal force (force exerted perpendicular to the surface your object is on; opposes gravity on a flat surface). There are two kinds of friction: static and kinetic. Static friction must be overcome in order to move an object. Once the object is in motion the friction acting on it is called kinetic. Static friction has a threshold of force that is needed to get the object moving but once the object is in motion it can be moved at a constant velocity with less force required.
Without friction what net force is needed to maintain a 1000 kg car in uniform motion for 30 minutes?
