Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Types of friction include dry, fluid, lubricated, skin, and internal. Friction can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire.
Friction is the rubbing of one body against another, the force that resists motion between two bodies in contact, or the clashing of opinions or interests. Learn more about the word history, synonyms, examples, and related phrases of friction.
Friction is a force that prevents or reduces the motion of two surfaces sliding across each other. Learn the formulas and examples of static and kinetic friction, and how they depend on the normal force and the coefficient of friction.
- what happens to co-efficient of friction ,when a body weight is doubled?the coefficient of friction does not depend upon weight.... as far as I know it is a function only of the materials?
- So, coefficient of kinetic / static friction cannot be a negative number?Correct. No friction is when the coefficient is 0 (zero). 100% friction (no movement) is when the coefficient is 1.
- Friction helps us to walk but in water why we cannot walkWe can walk on Land because the number of irregularities present on the surface are very plentiful, and differ from area to area, whereas in water,...

Friction is the force that makes it difficult for one object to slide along the surface of another or to move through a liquid or gas, or the disagreement or unfriendliness caused by different opinions. Learn more about friction in physics and everyday life with examples and translations.
Learn the key concepts, equations, and skills for friction, a contact force that resists sliding between surfaces. Find out how to determine the direction and magnitude of the friction force, and the difference between static and kinetic friction.
Aug 2, 2019 · Friction is a force that resists movement between surfaces in contact. It is caused by the interactions between the molecules that make up objects.
