Axel on bike
A lot of sports where players/ participants are chasing hundredths and personal records. Like in swimming, for an example, they really want to lower their friction to avoid being slowed down by the water. The same goes for 100-meter runners.
A lot of mechanical stuff also has low friction, to improve performance, speed etc. The vikings pulled their big ships sometimes up to several miles over the land by using rounded timber to pull the ships on, thus lowering the friction. Leonardo da vinci was the first known to make a modern ball bearing (and ball bearings are formed for reducing friction in amongst others an inline wheel).
Other than that, you might want to lower the friction to increase durability. This is what is done in objects who work using repetitive movements like back and forth-drilling, so that the object does not get stuck.
The axle of your car's wheels while you are driving.
yes because when they brake the friction is caused to reduce
Oil is used to reduce friction.
the main reason for doing so is that the surface becomes smooth n in terms of science to reduce "friction" that wud exist between the board n the striker due to which it will move more swiftly with lee deployment of power..!!
How does the flow of air reduce friction of the hovercraft in motion?
Professional bike riders want to reduce friction, because friction is a force of two objects rubbing up against each other, therefore slowing you down.
In many situations soap may be used to reduce friction. For instance, a carpenter may use soap on a wood screw to reduce the friction between the screw and the wood into which it's being driven.
No, sand does not reduce friction but increase friction.
Its reduce by following ways By polishing the surface use lubricants by streamlining by air cushion by converting sliding friction in to rolling friction
Lubrication to reduce friction. To increase friction step on the brakes.
yes because when they brake the friction is caused to reduce
TO REDUCE FRICTION: We can use fine powder on the carrom board to 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).
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
the factors that reduce in case of friction are the velocity and acceleration.
Oil is used to reduce friction.
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
by giving it better aerodynamics you can reduce friction. but also the faster it goes the more friction it gets.
