How can you increase braking distance?
By reducing the coefficient of friction between the brakes and the wheel OR between the road and the wheels.
What are advantages of wheel?
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
Why car use circular wheel?
Cars use a circular wheel because the design of a wheel results in static friction instead of kinetic friction (sliding). This makes it easier for cars to get traction and makes it easier to get moving and also stop. Other shapes just wouldnt be as efficient when trying to do everything.
Tell you some apllications of rolling friction?
A wheel is an example of rolling friction. An example of rolling friction would be if you took kyle leary and folled him down a hill. his fat touching the grond would create rolling friction
Was the wheel invented or discovered?
Actually the wheel was discovered first. When early men had seen them, they would have understand that it made transferring of load easier as, we all know that rolling friction is smaller than sliding friction. So, after that, they had made improvement in the 'WHEEL'. and then locomotives came into being.
What simple machine has a rope over a wheel?
A tire is a wheel and axle. This simple machine makes work easier by reducing the amount of force that needs to be applied to move a load.It is an Wheel and axle.
What is rolling friction and sliding friction?
I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
How do you find the friction of a pulley?
in the wheel because the treads on the wheel rub against the ground,causing friction
What causes wheel and wheel nuts to overheat?
friction
Breifly describe how applying the brakes to stop a bicycle is an example of force?
The brakes apply force to the wheel, causing friction which stops it.
How the wheel of car move?
friction
Example of friction?
Friction- A force that acts upon objects to resist change in motion. If you try to push a car up a slick, icy hill, it will be easier than trying to push the same truck up a dirt road with lots of gravel. Why? Because the dirt and gravel rub against the tires to help the truck resist motion.
