Question

Define friction.What are the factors affecting friction?Explain with examples.​

Answer 1

HEY MATE. .

friction: Factors Affecting Friction. ... Frictiondepends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth.

Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces.

What are the factors that affect friction and how can we predict...

Surface on which the object is moved or the nature of the surface. i.e., rough surface, smooth surface, liquids etc.

The weight of the object or the amount of force on the surface by the object.

Answer 2

Definition:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

factors affecting friction are:

1.smoothness of surface

2.normal force

examples:

●Rubbing both hands together to create heat

●A sled sliding across snow or ice

●Skis sliding against snow
