How does friction affect the motion of a vehicle in the context of tire surface road conditions including skidding braking force braking distance thinking distance and stopping distance?
Tyre surface: If the tyre is new, it will have surface with depressions which will offer more friction compared to old tyre whose surface-depressions are worn out and it is more flat, so it offers less friction. Therefore, new tyre will have less stopping distance, as force of friction is more. Thinking distance is affected neither by friction between tyre and road, nor by friction between brake and tyre. If road has a wet surface, it has less friction so the vehicle will skid farther, and vice versa. The braking force, i.e, friction between tyre and brake is unaffected by road condition or tyre surface. Hence the distance the vehicle travels WHILE retarding due to "braking force", is not same as stopping distance, because even when the wheels are stopped rotating due to braking force, the car will skid a little distance- this total distance is the stopping distance.
What energy is transferred when a vehicle stops?
Assuming the vehicle stops because the brakes are applied - it would be kinetic energy transferred to heat via friction with the brake pads and brake shoes (mostly). Some would be kinetic energy transformed to heat via friction with the wheels on the road and the turning parts of the axle, transmission, etc.
Effect of friction on the motion of a vehicle in the context of tire surface?
the more worn-out the tyre the lesser the friction produced.newer tyres are better in stopping cars as they can produce greater friction. the worn-out tyre has a surface which is plainer than the new tyre. lesser surface irregularities leads to lesser friction.
What determines the stopping distance?
Stopping distance as in braking distance: Braking distance refers to the distance a vehicle will travel from the point where the brakes are fully applied to when it comes to a complete stop. It is affected by the original speed of the vehicle, the type of brake system in use, the reaction time of the driver/rider and the cefficient of friction between the tires and the road surface.
Is friction always something we want reduce?
NO!You very much need to increase friction between car tires and the road surface in winter. Accumulated snow and ice can already reduce friction there to the point that stopping and steering the car becomes impossible leading to many severe and occasionally fatal accidents.Vehicle brakes also need as much friction as possible to efficiently stop the vehicle when needed.Sandpaper and other abrasives depend on friction to smooth and clean surfaces.etc.
How does kinetic affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph?
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
Where can friction be useful when it is high?
stopping an oncoming vehicle.
How does friction on tires effect the stopping distance of a car?
The more friction, the quicker the vehicle will stop, meaning less stopping distance.
What energy or momentum of a vehicle can be offset by allwoing an increase in stopping distance?
kinetic

What does a brake pad normally get used for?
A brake pad is part of the brake system used in machines such as vehicles. The brake pad has a rough surface which converts kinetic energy that causes motion into thermal energy, thus stopping the vehicle.
What energy is transferred when a vehicle stops?
Assuming the vehicle stops because the brakes are applied - it would be kinetic energy transferred to heat via friction with the brake pads and brake shoes (mostly). Some would be kinetic energy transformed to heat via friction with the wheels on the road and the turning parts of the axle, transmission, etc.
What is the science behind breaks?
The science behind BRAKES is that you use friction to convert kinetic (moving) energy into heat energy to stop a vehicle.
What is the difference in stopping time between 60mph and 30mph?
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
How could you use the law of conservation of energy to describe his trip down the mountain?
The potential energy present in a vehicle at the pot of a mountain gets turned into kinetic energy as the vehicle travels down the mountain. Eventually that kinetic energy is dispersed as friction turns it into heat.

How does the weight of a car effect the stopping distance of a car?
The more the vehicle weighs, the harder the brakes must work to stop it and the more distance it will need to stop the vehicle. However, large trucks can brake easier with more weight because weight adds friction which helps to stop the vehicle. This still doesn't fully compensate for the total stopping distance needed for a large vehicle. Basicly what he means is the heavier the vehicle the more friction it can create(slow it down) but it can add to the forward force iswell Or more precisely, the force of the vehicle going forward because of it's mass is still greater than the force of friction helping the vehicle slow down.
