Can friction never be eliminated?
Ans: Friction can never be entirely eliminated, because no surface is perfectly smooth, there are always some irregularities present in it.
Can we eliminate friction completely Yes or no?
Ans: The force acting on the two surfaces in contact which opposes the motion of one body over the other is called the force of friction. 2. Can we eliminate friction completely? Ans: No, we cannot eliminate friction completely.
Why can we never reduce friction to zero?
Complete answer: We can reduce the friction but we can never reduce it to zero because every surface will still have minor in them. A frictionless surface is not possible is not possible because the surface cannot have a zero friction surface. Due to friction force a body stops.
Can friction be eliminated on two rubbing surfaces?
When two surfaces slide over one another the tiny bumps push on each other. Friction causes a force on a surface which is in the opposite direction to its motion. Friction can be reduced by the application of lubricants.
Is friction is always undesirable?
The friction is undesirable in most of the cases.
What are the 2 ways to increase friction?
There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction between the tyre and the road.
Can we reduce the friction 20?
Friction can be reduced to a great extent by polishing surfaces or by using a large amount of lubricants such as oil, water, or grease but we cannot reduce friction to zero.
What affects the force of friction?
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.
What are three ways to reduce friction?
Generally, there are three ways to reduce friction: 1. The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. 2. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.
Which are methods reduce friction?
Make surfaces smooth by grinding
What can reduce friction?
A common way to reduce friction is by using a lubricant, such as oil, water, or grease, which is placed between the two surfaces, often dramatically lessening the coefficient of friction. The science of friction and lubrication is called tribology.
