Question

Explain 3 methods of reducing friction

Answer 1

$\sf\huge\underline{\underline{Answer:}}$

• Reduce the forces acting on the surfaces.

• Reduce the contact between the surfaces.

• Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.

Extra information:-

Friction is the force that opposes the relative motion between the two surfaces of objects in contact.

There are four types of friction: static, sliding, rolling, and fluidfriction. 

There are five laws of friction.

Examples of Friction :-

• Rubbing both hands together to create heat.
• An iron being pushed across material.
• A person sliding down a slide.

Formula of friction = F = μN to calculate,with N standing for the “normal” force and “μ” incorporating the surface.
