WebFriction Class 8 Notes - Chapter 12. The class 8 Science chapter 12 Friction, discusses friction and various factor affecting it. The force, which opposes the relative motion between two surfaces in contact is known as friction. It acts on both the surfaces. Listed below are factors that affect friction. WebMay 14, 2024 · FRICTIONAL FORCE It is a force which opposes relative motion between the surfaces in contact. f = μN This will be discussed in detail in later section. PSEUDO FORCE If a body of mass m is placed in … WebWith the increase in smoothness, the force of rolling friction decreases. Rolling friction is expressed as a product of load and constant to the fractional power. F = kL n. Rolling friction force is directly proportional to load and inversely proportional to the radius of curvature. F = μ × W r. my health suraksha
