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.
What kind of friction results when a wheel turns on its surface?
Rolling friction, I believe.
When a car is anticipating a turn isn't the steering wheel providing the centripetal force rather than the road friction?
No steering wheel won't provide the centripetal only the friction between the tyre and road provides the necessary centripetal. Steering would simply turn the wheels of the car to the desired direction.
Definition of a Wheel and Axle?
THE ROLLING ITEM THAT MAKES CONTACT WITH THE FRICTION SURFACE [WHEEL] THE THE DEVICE THAT TRANSMIT THE FORCE FROM THE POWER UNIT TO THE WHEEL. [AXLE]
Why is sliding friction less than static friction?
Because when an object is sliding on the other the molecules donnot get time to inter lock properly
What is the purpose of a wheel and axle?
The purpose of a wheel and axle is to reduce the total friction that acts against the linear motion of an object along a surface.
Prove that friction is a necessary evil?
Yes necessary evil. If friction is totally absent then no wheel could roll on the road. No chance of walking on the floor. We cannot hold even the pen. Same time too much of friction would bring a terrible loss of energy.
Why wheels are circle?
A wheel is circular to reduce friction with the road surface, and to allow a vehicle to move smoothly forward.
What is the resistance of one surface to the motion of another surface rubbing over it?
Friction. One example is the action of the brake blocks on a bicycle pressing against the wheel rim and causing friction enough to bring the bicycle to a halt!
Which wheel of vehicle will have more friction one having wider tire and one having sleek tire?
Friction or grip if it's friction i think the tyre with the most contact with the road surface. If it's grip then the one with the tread
How much friction is produced by brakes to stop a vehicle running at 80kmhr?
friction acting btw the road surface and wheel depends upon the braking retardation of the vehicle. every surface has its own friction coefficient which represents the maximum value , however friction can act in range from 0 to that max value , and this value depends upon the braking retardation.
What is rolling friction?
Rolling friction is when an object that is rolling/sliding/moving on a surface is slowed down or stopped, because of the friction of the two objects rubbing against each other.
