What will a car do when its tires lose part or all of their grip on the road?
The car will skid
What force allows Car tires to grip to a road?
friction
Why is rear of car lower?
the areodinamics of the car makes downforns and your car gets better grip on the road
Why does a car move away more easily on dry road than wet?
a car itself is pretty heavy, all the weigt of it is equally divided by the four wheels. A tire of a car has carves in it to make it have more grip on the road. The cars' weigt and the grip it has on the road combined is what a car keeps from slipping on a dry road when the road is wet it has less grip on the road but still the same weigt. so when your driving the kinetic energy caused by the speed of the car and the weigt can cause the car to slip. i hope this is a good answer for you but i know i have made alot of writing errors.
What helps a car grip the roads?
Rubber things called tires!
Why old and smooth tires are discarded?
Because they are dangerous to use on your car . -You would have NO grip on the road
How big is the frictional force when a car stops on a flat road?
Very big because it has no grip on the surface for the frictional force to stop and it takes time to stop the car.
What is the purpose of groves on car tires?
The groves are for traction, or grip on the road. Without them, cars would slip and slide a lot more.
Explain why ears skid on curves when the road is icy?
When a car is on a curve, centrifugal force tends to force it outwards. Normally, this force is resisted by the car's tires gripping the road surface. However, ice on the road reduces the friction and therefore the tires cannot grip so well.
Why does your car loose stearing control when accelerating?
If by steering control you mean the ability of the car to turn.. It is directly linked to the amount of friction or grip your car can generate with the road. A vehicles grip depends on road surface, the vehicle's weight and the compound of your tire, and it is therefore fixed. When you steer you are using the grip of the car to be able to turn, the harder (and faster) you turn the more grip you essentially "use". When you accelerate you are also "using" the grip to push the car forwards, again, the more you accelerate the more you use the grip. When you steer and accelerate at the same time you are using the grip for two jobs at the same time, therefore your amount of grip generated is "depleted" faster and your car slides along spinning your wheels. If you have a front wheel drive car and you accelerate fast then all the weight will transfer to the rear wheels and the front tires will lose the weight it had so the tires, which are powering the car, will overpower the steering and make it extremely touchy. On a rear wheel drive car the quicker you accelerate the more weight you get on the rear tires and because the front tires aren't "driving" you don't have the same steering problems.
Why a car with worn out treads on its tyres is more likely to skid?
Less grip on the road surface. Bald tires are also more likely to hydroplane.
What are the properties of road salt?
I think road salt it made of salt, gravel and sand. The salf lowers the melting point of the snow/ice, so therefore melting it, and the sand and gravel give a car grip.
