Question

define causes of friction
with example ​

Answer 1

Explanation:

Friction is a force that resists the relative motion between two objects or materials. The causes of the resistive force of friction are: Molecular Adhesion. Surface Roughness. Plowing effect.

Answer 2

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

The frictional force between two bodies depends mainly on three factors: (i) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

Everyday Examples of Sliding Friction:

• Rubbing both hands together to create heat.
• A sled sliding across snow or ice.
• Skis sliding against snow.
• A person sliding down a slide is an example of sliding friction.
• A coaster sliding against a table.
• A washing machine pushed along a floor.
• An iron being pushed across material.
