my car sways when driving down road at high speeds?

check your wheels,... are they properly aligned? Also go for computerised wheel balancing.\nAnd better be careful. Don't drive too fast till you get the prob rectified. If you brake suddenly then the car might skid or turn around.

the speeds are too small, so classical mechanics should be fine:\n\nthe speed of the car is 45-10 = 35mph

The force that pulls you towards the side of your car when you go around a corner too fast is actually inertia.  It's the same force that makes you fly forward when you hit the brakes too fast or sink into your seat when you lay on the gas.  According to Newton (I believe it's his third law), "an object in motion tends to stay in motion and an object at rest tends to stay at rest."  Well when you are in your car and you are moving in a straight line, your tendency is to keep moving in that straight line.  When you take the turn too sharply, the car is turning but your body's natural tendency is to keep moving in that straight line, so you get pushed up against the side of the car.  The same justification explains why you move forward or back when the car accelerates or decelerates too quickly.\n\nCoriolis force is a completely different force that is caused by the rotation of a sphere and the fact that the sphere is densest in the middle, with decreasing density as you approach the poles.  This change in density causes a force which makes moving things tend to move towards the equator of the sphere.

nothing-\nthe system of atoms inside your car is stationary relative to the baloon.

In brief.... friction.\n\nBasically, there is friction at the hub of the wheel which is acting as a force that slows down the wheel. In addition, there is also friction between the wheel and the air surrounding it (often called wind resistance). The two forces will eventually stop the wheel.

Yes, the helicopter will hover and will not travel to the rear of the car. If, and only if, your speed stays constant. In this case the car's speed  is 80mph. Any acceleration, even by 1mph, will cause your helicopter to travel rearward.  That's because speed is all relative. In this case the car, and everything inside of it, including the air, is traveling at 80mph.  The ground or road is at a stand still, compared to, or relative to the car which is moving.\nTry this simple demonstration. While traveling at a constant speed, 30mph, 50mph, or whatever, as long as your speed stays the same. Using two cups, raise one cup, which is filled with water, about a foot or two above the other cup. Pour the water into the the lowered empty cup. If you're good, you shouldn't spill a drop.  Now try it again, but this time as you are pouring the water, ask your driver to accelerate. You're going to get wet!\nIt's all about physics. Once an object is in motion, it wants to stay in motion. It takes an outside force to change that motion. In the case of your helicopter hovering in a car going 80mph, all matter inside your car wants to stay at 80mph, so accelerating or decelerating, by stepping on the gas pedal, or hitting the brakes is the outside force which will change that motion.\nHope I was helpful in answering your question?

Maybe the car designers like a bottom heavy babe! In fact CG or centre of gravity of the vehicles is at a low point if the heaviest weight is aaranged at the lowest point. Since engine is the heaviest part, it is placed at the lowest possible point to give car highest stability

Not sure about a website but the physics would be similar to what causes corrugations in a dirt road.  The vibration frequency would be related to the speed of the wheels.

Oh man, I really hope that's not true. I drive an old '92, 2 door Toyota Tercel. It used to be red, but it's faded to a horrible pinkish colour, except for the front fender and drivers door, which are bright red from when someone backed into my car. The fenders over the tire wells are sanded down, b/c they were rusted, and now they're sprayed white, and have been that way for months. It chug-a-lugs its way up hills going about 30km/h, and frequently stalls, and sometimes refuses to shift into reverse, which is quite annoying. So I guess that would make me a run down, hunk of junk that has to stop and sit down every few km. Greaaaat. I feel so much better about myself now. lol.

Some have the erroneous idea that it is brake failure during rain that causes the inability to control and/or stop a vehicle. This is not the case. What actually causes the problem is hydroplaning - the car's tires riding on a sheet of water causing loss of traction.  This condition occurs when water in front of your tires increases more quickly than the weight of your vehicle can push it out of the way through the treads on your tires. The increased water pressure causes the vehicle to lift slightly and ride on a thin layer of water which has built up between the tires and the road. This is the critical point when the vehicle becomes totally out of contact with the road, and becomes uncontrollable, the brakes seeming not to work. Actually, the brakes DO work, but when you slam them on during an emergency and it's wet, the tires are not making contact with the road. The wheels lock up, and your vehicle begins to slide on the water sheet. \n3 things that cause hydroplaning:\n1. Vehicle speed. Increased speed reduces wet traction. \n2. Tread depth on your vehicle's tires. The deeper the tread, the greater the traction. Bald tires are a safety problem.\n3. The deeper the water on the road, the sooner you will loose traction. However, even a very thin layer of water can cause loss of traction, even at low speeds. \nTo remain safe - remember to SLOW DOWN when driving in wet weather.

Between 15.0 and 15.5 the mods you listed wont help as much as you think they will. That time is probably that of a new car and not 1 that is almost 20 years old.

Similar to a shock absorber...helps make your ride less bumpy

plz find car position and after \nincrement in car position and car is moving

Go to your local auto-parts store and look in a repair manual (Chilton's or Haynes) for the year of the vehicle.\n Like the other has said it is probly the EGR valve. Or  a vaccuum valve for a cruise control. Anyway it should not be shaking. And holding it still causes the engine to run smoother? If this thing does not have any wires runninig off of it. Then it has a vaccuum leak. Reattach it to be solidly mounted or replace it.\n If this is a vaccuum valve then there should be a diagram of the vaccuum hose layout on a sticker under the hood. And this component should be named in that diagram.

The way to solve this problem is to decompose the forces acting on the car, but not in the x and y direction. Instead, decompose the forces in the direction of the incline and the normal force.\n\nHence, we have:\n\nF(friction) = μN, moving up the incline, and μ is the coefficient of static friction\n\nThen we have gravity acting on the car, and the component that's acting down the incline is = mgsinθ, where θ is the incline of 15°.\n\nFor the car to be safe in making this turn, the forces along the incline must be equal:\n\n(a) F(friction) = μN = mgsinθ = (1450)(9.8)sin(15°) = 3677.82 N\n\nBut the forces acting perpendicular to the incline on the car must also be zero:\n\nN = mgcosθ\n\nNow substituting this into the previous equation, we get:\n\nμN = μ(mgcosθ) = mgsinθ, this implies that the coefficient of static friction is:\n\n(b) μ = sinθ/cosθ = tanθ = tan(15°) = 0.268

If the coolant level is dropping, it is going somewhere.  If you can't find any leaks or see coolant on the ground then it's probably the head gasket.
