What are the 2 ways in which friction can be reduced?

Force | Short/Long Answer Questions

  • Polishing the rough surface.
  • Oiling or lubricating with graphite or grease the moving parts of a machine.
  • Providing all bearings or wheels between the moving parts of a machine or vehicles reduce friction and allow smooth movement as rolling friction is less than sliding friction.

How can we reduce and increase friction?

Grease is added between the moving parts in machines, to reduce friction. Another method of reducing friction is by using bearings. When ball bearings are introduced between two surfaces friction is reduced because of the freely rotating metal balls. To increase friction, the surfaces in contact have to be made rough.

How can we reduce friction Brainly?

Answer:

  1. Friction can be reduced by making the surface smooth by polishing.
  2. Friction can be reduced by applying lubricants (like oil or grease) to the rubbing surface.
  3. Friction can be reduced by using wheels to move objects.
  4. Friction can be reduced by using ball bearing between the moving parts of machine.

What is friction and limiting friction?

The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.

What are some common ways of decreasing friction?

Make surfaces smooth by grinding

  • Lubrication
  • Streamlined body
  • Reduce pressure or weight on the object
  • Reduce contact between surfaces by electrostatic magnetic levitation etc
  • Use rolling friction instead of sliding friction
  • Use fluid friction instead of the dry friction

    • How can you decrease or increase friction?

    We can reduce the friction by using lubricant and increase it by making the surface rough and removing the ball bearing, lubricant, etc. Another important invention similar to the wheel is the invention of a ball bearing. It was possible to reduce the friction greatly between the surfaces by using ball bearing.

    What things can reduce friction?

    Friction between moving parts is usually reduced by introducing a substance between the moving surfaces. This process is called lubrication. The substance introduced is called a lubricant. Common lubricants are oil and grease. Ball bearings are also used to reduce friction. Ball bearings change sliding friction to rolling friction.

    What are three ways to increase friction?

    For practical purposes, all three of these effects do the same thing: generate friction. Picking surfaces that are abrasive (like sandpaper), deform when pressed (like rubber), or have adhesive interactions with other surfaces (like tacky glue, etc.) is a straightforward way to increase friction.
