Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is caused . mostly by . the . electromagnetic . interactions of particles within molecules at the surfaces of objects in contact. While these interactions can be rather complex, their combined effects can be reasonably approximated with a decent amount of consistency.. Happy Valley-Goose Bay. Peacetime Disaster Plan.

Friction is the resistance to the sliding, rolling, or flowing motion of an object due to its contact with another object. . When a moving object comes in contact with another object, friction is the opposing force that slows or stops the moving object. . What factors affect (the size of) friction?. Survey says:.

Friction is dependent on the texture of the surfaces. Friction is dependent on normal force. motion. friction. What do you Remember about Friction?. Temperature in metal forming. For any metal, the values of K and n depend on temperature. Strength and strain hardening are both reduced at higher temperatures. These property changes are important because they result in lower forces and power during forming. In addition, ductility is increased at higher temperatures, which allows greater plastic deformation of the work metal. For these reasons the forming processes can be classified as:.
