In addition you will investigate the difference between static and kinetic friction.

Physics friction lab answers. F f µf n friction force coefficient of friction x normal force remember if it is not moving it is a static force and we must use the static coefficient µ s remember if it is moving it is a kinetic force and we must use the kinetic coefficient µ k if we have a situation that just states friction and does not define the type of friction or state of motion we can use the generic version shown above. The factors being tested will include the effect of surface texture weight and surface area contact on friction. You will apply a horizontal force to a block of wood loaded with weights in order to pull the block at constant velocity across a horizontal plane.

Surface will double the force with which the object presses against the surface and therefore double the friction that must. You will measure frictional forces using a spring scale to measure the force. Static friction force fs is a force between two objects that are notmoving relative to one another.

In this lab you will investigate the factors that affect friction. What factors affect kinetic friction. Our lab uses the force of gravity in order to find the maximum static friction force on an object before it turns into kinetic friction.

The figure shows a graph of the friction force on this block as a function of the pull. The box has a mass of 20 kg and a force of 200 n is pushing the box to the right. This will help in the understanding of how static friction will either increase or decrease due to the mass of the object.

We can rewrite our two variations of the friction equation to be. The pull gradually increases until the block begins to move and continues to increase thereafter. On a flat surface the normal force equals m mass g acceleration due to gravity because the normal force pushing up on the mass must equal the force of gravity pushing down on the mass so that the object is at rest and not accelerating.

Applied force must overcome the force of static friction. Friction lab mrsirwinhamilton physics force worksheets with answers friction gravity and elastic middle sound worksheets high school physics with answers best. According to velocity friction may be classified into static friction force fs when velocity 0 and sliding frictionforce fk when velocity 0.

Therefore the force of friction m g coefficient of friction. Be overcome to keep the object moving. Friction is a force that always opposes the motion of an object.

Force f is applied to the block to the right. In this activity you will examine how static and kinetic frictional forces vary as the normal force between an object and a surface is changed. Physics q a library in a laboratory experiment on friction a 135 n block resting on a rough horizontal table is pulled by a horizontal wire.

Friction lab data surface mass g incline force n investigating the factors of friction carpet desk book desk desk desk desk desk desk ramp ramp ramp what factors affect static friction. The ratio of the friction acting on an object to the force with which the object presses against a surface is called the.
