Maximum force due to static friction = fs = μsN. and 4. PROCEDURE. Note to students: A large amount of data will be taken in this experiment. To aid you in 

Two surfaces rubbing against each other will have some amount of friction. You can have situations with where you might not think about friction, such as sliding across ice (low friction) or wheels rolling on a street (high 3 The maximum friction force, F MAX, which can be reached between two surfaces in contact is known as limiting friction. As friction is a contact force, we might ask how it is related to the normal contact force. Carry out an experiment to investigate how the maximum friction force, F MAX, varies with the normal contact force, N. You will need: forces for a given situation. An inclined plane with a slope θ exerts a normal force N=mg cos θ on a body with mass m. If the body is at rest (or moving with constant speed), the upward friction force must be F= mg sin θ to counteract the tangential component of the force of gravity 6.

Friction is a force that resists motion. It involves objects in contact with each other, and it can be either useful or harmful. Friction helps when you want to slow or stop a bicycle, but it is harmful when it causes wear on the parts of a machine. For the next experiment, turn block 1 such that the smaller surface area faces the table and attach it to the force scale. Now measure the static friction force as before by making note of the force before the block begins to slide. Repeat this measurement five times to obtain multiple data sets. Friction is a resistive force, one that damps out motion in dynamic systems and prevents movement in static systems.

Contact forces, as the name implies, rely upon physical contact to act on a body. Field forces require no physical contact to act on a body. Friction is a contact force.
