Friction is a cause of lost energy and inefficiency. But it is critically important to have friction as regards automobiles. The most important use of friction by vehicles is that involving their contact with the ground. Without friction, there would be traction, which would translate into no acceleration and no control of the vehicle. Think this through and it will become clear.
What else can I help you with?
Does a pulley use friction?
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
Does friction always oppose the relative motion of objects?
No all ways it will not oppose the relative motion.Best example is the tyre of automobile, BeltIn this case short term bonds are formed between the road and automobile tire (these bonds nothing but friction or Grip for the tire) these bonds are very short term (i.e they lost with in few Millie seconds) .
Should one add static friction and kinetic friction together to find the total friction force?
No, static friction and kinetic friction are separate forces that act in different situations. When an object is at rest, static friction opposes the applied force. When the object is in motion, kinetic friction opposes the motion. To find the total friction force, you would just consider the friction force relevant to the situation.
Which parts of a bike use friction?
The brake pads against the wheel rims or disc rotor are the main components on a bike that use friction to slow down or stop the bike. Additionally, the tires gripping the road surface while pedaling or cornering also rely on friction to provide traction.
How can you increase the magnitude of friction between two surfaces How can you decrease the magnitude of friction?
To increase friction, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or use materials with higher coefficients of friction. To decrease friction, you can use lubricants to reduce surface roughness and create a barrier between the surfaces, reduce the normal force acting on the surfaces, or use materials with lower coefficients of friction.
What force causes an automobile to move?
forward friction on the tyres from the road..
Why do new automobile tires have deep grooves?
It is because there must be a friction between the tyres of an automobile and the road.it is for the same reason that special kinds of grooves are made in tyres so that they offer the required amount of friction.
What is a example of how friction can work for us?
Automobile brakes and clutches require friction. We also need friction between the tyres and the road when we accelerate or when we brake or when we turn a corner.
Why are automobile tires provided with a rough surface?
because it provides better friction
Why does the pressure in an automobile tire increase if the automobile is driven for a while?
The tire heats up do to the friction with the road, a heated gas in a set volume will increase in pressure.
Why is that an automobile can travel faster on a concrete road than on desert?
Less resistance/friction on concrete.
Why an automobile can travel faster on a concrete road than on a desert?
Less resistance/friction on concrete.
How do you use automobile in a sentence?
This automobile sounds funny.
How do liquids in hydraulic brakes help stop an automobile?
Liquids in hydraulic brakes help to stop an automobile by creating pressure and moving a set of pistons to generate force. This force is applied outward and causes friction that stops the automobile.
Need of a gear box in automobile?
to get different speedto get reverse speedhelps the vehicle to move against friction
What is the use of automobile?
Transportation.
Use of center lathe for Friction welding?
Centre lathe can use for friction welding.
