RBSE Class 8 Science Chapter 12 Notes Friction

→ Friction opposes the relative motion between two surfaces in contact. It acts on both the surfaces. Friction depends on the nature of surfaces in contact.

→ Sliding friction comes into play when an object is sliding over another. Sliding friction is smaller than static friction.

→ Friction can be increased by making a surface rough. The sole of the shoes and the tyres of the vehicle are treaded to increase friction.

RBSE Class 8 Science Notes Chapter 12 Friction

→ Friction can be reduced by using lubricants.

→ When one body rolls over another body, rolling friction comes into play. Rolling friction is smaller, than sliding friction. In many machines, friction is reduced by using ball bearings.

→ Fluid friction can be minimised by giving suitable shapes to bodies moving in fluids.
