The force resists motion and in most cases the force acts in the opposite direction to the motion.
Friction with the floor.
The coefficient of friction between two surfaces is a difficult value to measure.
Having the right amount of friction between the floor and the soles of the shoes of the person walking on it is essential.
Slip and falls occur when the coefficient of static friction is low enough to allow the friction force between the shoe and the floor to be overcome by common horizontal forces related to standing and or walking.
It moves 1 or 2 meters and then stops.
Friction is desirable and important in supplying tractionto facilitate motion on land.
1 push an empty box on a smooth floor and then let go.
Inclined plane force components.
A force of friction is any force that opposes the motion of an object due to the contact of the object with other bodies.
Until now in physics you ve probably been ignoring friction to make things simpler.
Ice accelerating down an incline.
You see as we stand or walk there are horizontal forces present between your shoe and the floor.
Assume that there is essentially no friction between the ruler and the wall.
Static friction to investigate static friction you will first tilt a stiff plastic ruler with one end on the floor and the other end against a smooth wall at an angle 0 as shown below.
Slips and falls happen when the coefficient of friction cof between the two surfaces is insufficient.
Now it s time to include this very real force and see what happens.
This example won t go into detail about how that is done.
Most land vehiclesrely on friction for acceleration deceleration and changing direction.
Sudden reductions in traction can cause loss of control and accidents.
Friction describes the force between two surfaces when you try to move one across the other.
Slip resistance testing or floor friction testing is usually desired by the building s owner or manager when there has been a report of a slip and fall accident when there has been a report of a near accident or preferably before the flooring is installed on the property.

It most cases it s done empirically or in other words through physical experiments.
Next the coefficient of friction between the surfaces must be determined.
Let us look at the following experiments.
