Lubricants such as oil, grease, and graphite are commonly used. However, simply keeping a liquid coating (even water) may help reduce friction. In many applications, surfaces can be made with very smooth substances such as polished metal, ceramics, or Teflon.

How do you increase the efficiency of pushing a concrete block up a wooden ramp?

Reduce the friction of it and the ramp, for example, mounting it on wheels.


The wheels and gears of a machine are greased in order to decrease?

Friction.


What does friction allow us to do?

In general, friction acts to prevent objects in contact with each other from moving with respect to each other. Friction keeps your furniture where you place it. The friction between your feet [or shoes] and the ground enables you to walk. When you apply the brakes in a car, friction causes the wheels to stop rotating . Friction holds a screw or nail into a board and a nut onto a bolt. Friction between your fingers and an object allows you to pick it up. Friction is proportional to surface roughness. A measurement of the force needed to overcome friction can be used as an indicator of a surface's roughness/smoothness. When friction is used to reduce relative motion (or to get objects moving), a portion of energy needed to do so is dissipated in the form of heat. This is why a car's brakes get hot and why a nail pulled out of a board can feel warm. Usually, this heat is just a waste byproduct, but it can be useful. The friction of rubbing your hands together will warm them, and the heat of driving a nail into a board can be used to temporarily melt the adhesive on 'cement coated' nails.


Can friction produced by wheels of moving train generate electricity?

yes we can produce electricity by fixing dynamo in traction wheels so heat is produced when the friction of train wheel & track so the dynamo generates an power D.C SUPPLY and is converts into Ac supply so we can use that energy for electric trains use of lights and fans....


What can water wheels be used for?

It converts the energy of the flow of water into something more useful. The water wheel can turn a wheel which grinds corn, grain, etc. More modern uses are to converting the energy into electricity. Please give me a trust point.

How do wheels reduce friction?

Wheels reduce friction by creating rolling motion instead of sliding motion. This reduces the amount of surface contact and friction between the wheel and the ground. Additionally, wheels can distribute the weight more evenly, further decreasing friction.


What kind of friction can help reduce friction?

I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).


How does the use of car brakes reduce friction?

When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.


Why are ball bearing used in wheels?

Machine parts use ball bearings to reduce friction, making it easier to move the moving parts and producing less wear on the parts.


Why do wheels help reduce friction between a dresser and bedroom floor?

because the wheels roll,and without the wheels then the bottom of the dresser would just slide and create static electricty,also know as,friction!:)


What stuff can reduce friction?

* lubricanting like oil, greese, etc. * by using ball bearing * polishing * stream lining Water can reduce friction. Also, round things like wheels and straws can reduce friction. Things that are placed on wheels, straws, pencils, etc. can move far with a soft push.


How do you reduce friction on a bike?

You can reduce friction on a bike by keeping the chain clean and lubricated, ensuring the tires are properly inflated, and using high-quality bearings in the wheels. Regular maintenance and tuning of the bike will also help reduce friction and keep it running smoothly.


How wheels work on a car?

Wheels and axles help reduce friction and allow a heavy objects like a car to move around easily.


Why do wheel reduce the force of friction?

Wheels reduce the force of friction by minimizing the contact area between the object and the surface it's moving on. This decreases the amount of friction generated, allowing the object to move more easily. Additionally, wheels allow for rolling motion, which is more efficient than sliding motion, further reducing the frictional force.


What are the two types of friction that affect a mousetrap car?

The two types of friction that affect a mousetrap car are rolling friction, which occurs between the wheels and the surface of the ground, and sliding friction, which occurs between the axles and the wheels. Both types of friction can reduce the overall efficiency and speed of the mousetrap car.
