Question

4. (a) Define friction. What are the factors affecting friction? Explain with examples.
(b) What is the cause of friction? ​

Answer 1

Explanation:

1)The force that opposes the motion of an object is called friction. Example: when we walk, friction acts in opposite direction we apply force to walk. The factor affecting friction are: ... The weight of the object.

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.

$\green\implies$a) The force that opposes the motion of an object is called friction. Example: when we walk, friction acts in opposite direction we apply force to walk. The factor affecting friction are: ... The weight of the object.

b) Causes of Friction: Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
