What is called the force between the tire and the road?
resistive force (friction)
What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?
Really? A coefficient of friction of 7? Unheard of. Probably 0.7 Use F = mv^2 / r where F will be the centripetal force as well as the frictional force, (mu)mg. Solve for v.
Why does friction increase as speed increases using particles?
The faster you go, the more air you have bashing into your surface. Imagine the molecules comprising air were the size of basket-balls. at walking speed, you'd only have 5 or 6 basket balls hitting you in the face every minute or so and they'd only hit you at walking pace. When you move up to running speed, you suddenly have 15 or so basket balls hitting you in the face every minute at running pace. Riding on a bicycle, you have between 30 and 40 basket balls hitting you in the face every minute at a very high speed. So the faster you go, the more basket balls you have hitting you at a higher speed. These two factors multiply together to give the friction force which increases as a square factor of your speed, (i.e. increase speed by 2, you have 2x the basketballs hitting you 2x as fast which equals 2x2 = 4 times the friction force). I hope this explanation is adequate. Cheers. by michelle obispo
Why is friction different from other forces?
Friction is the force exerted on a body when the body pushes against the microscopic obstacles in its path. Therefore , it is basically a reaction to the force exerted by the body.It comes into play when a body moves on a surface which is not completely even ,even at the microscopic level. Another difference is that the friction force is constant beyond a threshold for a given homogeneous surface,even if we increase speed of the body. Friction is essential for our movement and to keep in place things such as a knot. The resisting force employed usually by the resisting obstacles is the electromagnetic force.
Coefficient of friction of road and tire?
Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre Wet Road: 0.4 Dry Road: 0.7 This is the average coeffecient for these conditions again it can vary
What is called the force between the tire and the road?
resistive force (friction)
When you use the handbrakes on a bike what force do you apply?
The force you apply is technically called applied force. It is transfered and used to move the brake pads together. At that point, the frictional force between the brake pads and the tire slows down the tire.
What force gives wheels traction to grip the road?
Friction between the tire rubber and the road give traction.
What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?

Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
What are the frictional forces while riding a unicycle?
there's friction between saddle and butt, between shoes and pedals, between tire and rim, between tire and ground.
Why is the force on the steering greater when the tire is flat?
There is more surface area contact between the road and the flat tire translating into more friction between the two surfaces, which increases the amount of force required to change direction.
The force that keeps each tire from sliding on the road is called?
traction
Would the friction between a tire and the road be increased by a wide rather than a narrow tire?
No
When is friction a useful force that acts between objects?
Most forms of conventional movement require friction. For example, a car could not go anywhere if not for the the friction between the rubber tire and the road surface.
The weight of a car is 8400N Each tire supports a weight of 2100N The pressure exerted by each tire on the road is 20 Ncm How do you calculate the area of each tire in contact with the road?
Each tire supports 2100 N, and the pressure exerted by each tire is 20 N per centimeter2, so Pressure = Force / Area Pressure = 20 N per centimeter2 Force = 2100 N rearranging the equation for Area Area = Force / Pressure Area = 2100 / 20 = 105 centimeter2 So each tire has 105 cm2 touching the road.
How does tire tread increase friction between tire and road?
tires are made of rubber and rubber can cause friction
