The magnitude of the frictional force has two forms: one for static situations (static friction), the other for situations involving motion (kinetic friction). What follows is an approximate empirical (experimentally determined) model only. These equations for static and kinetic friction are not vect...
Calculate the magnitude of static and kinetic friction.Friction is a force that is around us all the time that opposes relative motion between systems in contact but also allows us to move (which you have discovered if you have ever tried to walk on ice). While a common force, the behavio...

The coefficients of static and kinetic friction between A and B are and , respectively. B is placed on a frictionless tabletop. The system is initially at rest, and then a horizontal force F is exerted on A. In order to make sure that there is no relative movement between A and B, ...
For example, a block of ice with a mass of 400 kg is pushed over a frozen lake. The coefficient of friction between the two surfaces is 0.05. The friction force acting on the ice block is equal to: A table of static and dynamic coefficients of friction between some materials is shown ...
The coefficients of static and kinetic friction between block 1 and the surface are µ and µ , respectively. Block 1 is again chosen so that s k M = M 1 . (b) Derive an expression for the maximum value of M2 that would allow this system to remain in equilibrium. Express your ...

» Above a threshold force, objects begin to move and kinetic friction becomes relevant. – Maximum static friction: = F Fs,max s nμ, where μ s is the coeff i cient of static friction. – For a given pair of objects, μ k < μ sTension• A pulling force exerted by a rope ...
1.5 whether the movement ofobjects friction hinder?Answer: not necessarily. Forexample the car forward, between the wheels and the road in fact there are twokinds of friction: static friction and rolling friction. The former is drivenby the driving force of the vehicle forward, the latter is ...
