Does the size of the wheel change the speed of the vehical?

given that you sustain the wheel with enough torque to maintain the angular velocity of the wheel, you will increase the speed of the vehicle. the tangential velocity is equal to the angular velocity multiplied by the distance from the center of rotation. this means that bigger wheels mean higher speed and smaller wheels a lower speed, given that the angular velocity is the same. the downfall is that you would be needing more power or torque for bigger wheels

It really depends on the vehicle and the driver. If you are experienced with manual transmissions, most "normal/everyday" cars are faster in manual. However, there are some high end models whose auto is faster (even driven by a novice) than the manual version driven by a professional race car driver. One example of this is the new (2007) Porsche 911 Turbo, which goes 0-60mph in 4 seconds with a manual transmission (with professional test driver) and goes 0-60mph in 3.6 seconds with the automatic transmission (in auto mode, not tiptronic).

LOL, Technically Yes, any smaller 5th wheel would work. You would have to modify the Frame and mount the 5th wheel hitch on top, but, technically it would work if the tongue weight is not too much, may need to adjust the axles of the 5th wheel. Due to the power of the engine I would get the smallest 5th wheel available. People have done many strange things with vehicles over the years, and, some worked!!! Be sure you do have Electric brakes on the Trailer too, I doubt the VW brakes and weight of the car would have much stopping power. I hope your thinking 5th wheel and not a bumper pull, but, it will work too.

Another way to see it is to consider acceleration versus constant speed. If you're going 60mph your position is increasing at that constant rate, but if you're pushing on the accelerator your speed is going 60,61,62 etc.. so your speed (which is your position vs time rate) is increasing. That is a varying rate. Doesn't have to be strictly increasing though. You could be speeding up then slowing down then back up again. Or maybe accelerating or decelerating faster, then slower. It can be any combination as long as you're not constantly going at one speed.

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.

No. The velocity of the wheel is changing as the car moves (because velocity indicates direction). So as the car moves forward, the velocity of the surface of the wheel is continuously changing.

All the above. the taller wheels will need more power and torque to move.

LOl oh wow, i never heard that, i thought if u tighten up it does make them c/um FASTER. LOL

They WILL affect your car..that is, if you manage to fit 285/50 x 20" on a merc E. The ABS will not engage properly, nor will the traction control, if u have any. U'll burn away the clutch faster as u start-off, u'll wear-off the brakes in no time as u try to stop the 20s from spinning. There's also the added weight. More than that, since all mercs are RWD, u should think about fitting different tires with different widths for the front and rear axles (ie wider at the rear axle). Good Luck anyways!

Yes, but it will take some experimentation at lower speeds and consultation with someone who has done it successfully. Your undriven wheels will rapidly decelerate upon reaching the ramp, and since their rotating mass is much smaller than the car's mass the forward jolt on the car will be small. I would think you'd want to have the driven wheels unpowered when they make the transition from the road to the ramp. Even so those wheels will have a larger associated rotating mass since the drive train up to and including the driven plate of the clutch (you are going to use a manual shift, aren't you?), is included, which will make the transition jolt bigger but still not energetic enough to drive you any significant distance up the ramp \nNote that the car's behavior will differ between front- and rear-wheel drive. Assume the general strategy is to have enough initial velocity relative to the truck so that the coasting car will roll up the ramp far enough to get the rear wheels on the ramp. If that is done successfully, you can then apply the brakes, downshift to first and proceed as you would in a hill start. However if you don't quite get far enough and the rear wheels are still on the road, you are better off with a front-drive car since you can then just pull the car ahead with no problem. A rear-drive car would either have to start the maneuver all over again or risk making the transition under power.\nDisclaimer: I've never done this, and you should consult someone who has!

Not exactly, since your butt would stay on the outside and your head would be wound somewhere around the steering wheel! Perhaps things would be the same as a bug if you weighed a little less than a kilogram! Hey, let us know what happens the next time you do it! :)

Of course...any change in diameter will affect the odometer.  But the change would be too small to notice under normal conditions.

OK here goes\n\nFaster = higher top speed \nQuicker = accelerates faster\n\nFor the street quicker is much more important.\n\nTop speed is not influenced by weight, in fact more weight makes it easier to handle at high speed. All that influences top speed is drag and horsepower.\n\nAcceleration is influenced by the  power to weight ratio, traction, gearing, and a bit by drag.\n\nRsx type-s has a top speed of 124 and 1/4 mile of 15.16/93.24\n\nAccord V6 I was unable to find the info for either but I think it would be both faster and quicker.

It has only partly done so.  Other than resistance from consumers meaning old and metric systems are quoted together on food and drinks, and clothes sizes and other bought goods (except for pretrol for some reason) - Speedomoters in cars and speed limits remain in miles - not kilometres/ per hour.  The introduction of the dual system was in the early/mid seventies shortly after they joined the EEC.

This question is too vague.  But I can tell you that tires will make the biggest difference both cheaply and quickly.

The Trolley + Child being one single system, the speed of the Centre of Mass would not vary. It would remain the same velocity V.

The simplest answer is balance.\n\nIt isn't energy - you expend the same whether you're pedalling or walking to achieve the difference in altitude.\n\nHowever, the cadence (rate at which you spin the pedals), and the gearing between your foot speed and the (rear) wheel speed  is a factor in the how fast the wheels move ... and therefore in how good a gyroscope you have. Faster feet (and faster wheel speed) means better balance.\n\nClimbing a hill, you trade off mechanical advantage for foot speed, at the expense of wheel speed. The amount of strength expended to keep the bike upright (by tweaking with your upper body) increases after a certain foot/wheel combination is achieved. Thus it becomes "harder" to do.\n\nThe other point of balance has been referred to earlier by another answerer; if the center of gravity (of the system, which includes both the rider and the bike) advances too far forward, there's a loss of balance. The same occurs if it moves too far rearward. At intermediate points, it requires more concentration and percieved effort to keep everything "rubber side down" ... thus it appears harder to accomplish some maneuvers on the bike.
