Because the tires on the car make contact with the surface you are driving on and they rub together. This gradually slows your car down.

What is the force that brakes use to stop a car?
FrictionMost cars use friction between the rotor and the brake pads to slow and stop a car, however, in some newer cars, dynamic braking is used, which reduces friction and for hybrid or electric vehicles, regenerates power and feeds it back to the batteries.
To stop friction what must be used?
Lubrication stops friction. If you put lubricant on a surface, there should be no friction
What type of friction would be used to cause a book to slow down and stop when pushed?
Sliding friction causes a book to slow down and stop when pushed. ------- Might also be known as dynamic friction.
What effects does friction have on a moving object?
All kinds of friction cause moving objects to slow down or stop. Friction can be quantified as a force resisting motion which is proportional to the weight of the object, for an object lying on a flat surface. The frictional force is found by multiplying the objects weight by a coefficient of friction, which is usually less than one, but can be higher than one (for example with rubber tyres on dry tarmac). Therefore friction requires a greater force to be applied to move the object. A similar coefficient called the drag coefficient is used to quantify air resistance in vehicles and aircraft-the faster you go the higher the frictional force, in this case.Friction is a force that acts against a moving object to slow it down. A type of friction is air resistance.Friction opposes the direction in which the object is moving, causing the object to decrease in speed, or stop all together.
What friction is used when an object sits still?
Static friction resists an object from moving when at rest (still) with respect to the surface it is resting on or in contact with. Kinetic friction, or dynamic friction, (normally what we think of when we say 'friction') describes the friction that occurs when one body moves relative to another body and when both bodies are in contact with each other.
What is used in cars to protect the moving parts?
Oil and grease is used to eliminate friction between moving parts.
The function of a brake drum or rotor is to act as?
Friction device used to stop a moving vehicle.

Why do cars need oil?
cars are made up of mechanical moving components due to continuous moving ,there is friction between parts to reduce friction and longer life of car we need oil fro car Cars need in in order to lubricate the moving parts. In general, motor oil is the most commonly used oil in a car. This oil is meant to lubricate moving parts such as cam shafts, crank shafts, lifters and pistons. Without oil, these metal on metal contacts would heat up and eventually melt due to the friction created. Oil helps by lubricating the surfaces where moving metal parts meet. In addition, oil helps absorb and dissipate the heat generated by the friction.
What is the by product of the friction used to stop?
heat
To stop friction what must be used?
Lubrication stops friction. If you put lubricant on a surface, there should be no friction
What force is used for brakes used to stop a car?
Friction
How is friction useful skateboarding?
Voodoo 13: Friction is a friend and enemy when skateboarding.. Friction slows you sown and heats up your wheels and wheel bearings, but it also helps you slow or stop and keeps you from sliding out of control when turning..
What is the brake pedal used for?
The brake pedal is used to bring a motorized moving vehicle to a safe stop. Vehicles such as cars, trucks, bicycles, and all utilize a brake petal mechanism.
What can stop a car from moving after starting?
Generally, cars stop moving for one of three reasons. Most commonly, the driver has used the breaks. The car can collide with some heavy object, such as a tree. (Driving off a pier into the ocean also counts.) Or, the car has run out of gas and eventually will stop moving because of air resistance if for no other reason.
What type of friction would be used to cause a book to slow down and stop when pushed?
Sliding friction causes a book to slow down and stop when pushed. ------- Might also be known as dynamic friction.
Why is grease used in machine?
Grease and oil is used in machinery to prevent the moving parts from wearing out too soon due to friction.
