when driving how come a fly wont hit windshield while inside car even going around corners? at any speed?

Because the air and all objects inside of the car are going the same speed as the car, try driving around a corner with a helium ballon. If you take a right corner the ballon will go to the right side of the car while you go to the left side.

When they fly into a ceiling, their feet stick on the ceiling same as with a wall. Flies, like all insects have 6 legs, 2 in the "front" and 4 in the "rear" --\napproximately. As the fly approaches the ceiling, it "reaches up overhead"\nand grips the ceiling with its two front legs. It's forward momentum carries the rest of the fly in the direction of flight. It then does a "180 degree"\nflip planting its 4 rear legs on the ceiling, landing in the opposite direction as the initial direction of flight.\n\nThis is not as bizarre as it sounds. Human gymnasts on the uneven bars perform similar trajectories in some of their exercises.

The driver cannot see the lighting of the lights on the road as teh car will be travelling at the same speed of light. The car will be on the same point of the road where the light is falling. Because the car will travel that distance along with light which is about to hit the road. let me explain. Let us assume that car is "c" lights are "l" and the lighting is "r". So their positions will be some thing like this\n     c   lr\nAs lights will be before car.\nNow lights have released the light and the light is hits the ground and at teh same time car reaches that point.\n           cr   lr1\nr1 is the light that is released at that point of instant.\nI had explained a lot and in that effort I had missed the point that this cannot be explained like this. LOL.

Trick question?  Frozen rubber hitting plastic or wood doesn't work very well.  Think small, solid object flying at 100 mph.

The 'do not touch metal inside a car' is an urban legend.\n\nThe car body acts like a Faraday cage. \n\nA Faraday cage is an enclosure designed to exclude electromagnetic fields. It works on the basis of Gauss's law, one of Maxwell's equations. The Gauss's law describes the distribution of electrical charge on a conducting form, such as a sphere, a plane, a car, etc. Since like charges repel each other, charge will "migrate" to the surface of the cage and not affect anyone inside. Also, since the human body has a higher resistance then the metal, the charge would not travel though the body, as it will always take the shortest way to the ground/path of least resistance. \n\nIt is named after physicist Michael Faraday, who built the first Faraday cage in 1836.

while driving my motorcylcle along mississippi river north of st louis at about 60 mph, i hit a dragonfly.  i splattered all over my glasses after it hit my cheek, and it stung quite a bit.  i had to stop  as i was pulling my bike off to the shoulder, all i could smell was the scent of dead fish and bugs.  it was from the bug guts.  \n\nhitting a bird at 180 mph would probably have broken a jaw bone.

Heat air goes up in circles and flies just use air to help during their annoying activity. \n\nIn center of your room, air will invcrease temperature and being pushed by your walls temp. Then, in middle of it, you will have a small imperceptle "hurricane" of hot air. \n\nYou will hardly see it in ope spaces and excelent curiosity gift; \n\nlooks that you have a lot of free time.

If the fly flies in while the box car os still, the doors are shut and the fly doesn't land, the fly will move relative to the outside, not the train.  Once the fly lands, It will take the properties of the train as its frame of reference.  So, it will move around the box car as if it were still.\n\nIf the box car is open, you are "opening" the system, in that the box car is not it's own environment.  Turbulence, etc, will affect flight.

Yes. The car acts as a Faraday cage, so the current goes around the surface and does not harm the occupants.

When the car is traveling at 100 mph, everything at rest with in the car is also traveling at 100 mph, this includes you, the air, any any flies present.\n\nWhen you suddenly stop the car, you are not just stopping the car bu also everything inside as well.\nPretty much everything within the car slows down/stops at the same rate (assuming ample "Stopping" forces).  So when you step on the brakes, the fly slows down too, despite the fact that it is not physically connected [strapped down] with the car.\nThe fly does not slam into the windshield for the same reason the back of the car does not turn into a vacuum.\n\n\nEDIT:\n"memento mori", inertia would be a reason why the fly might indeed hit the windshield, not why it might not.\nInterial is the property of matter which says that objects tend to continue doing what they are doing (objects at rest stay at rest, objects in motion stay in motion, ...Newton's 1st law).\nIf the fly was in motion and you slammed on the breaks, the fly should stay in motion, not come to a rest.....unless of course, something did work on the fly (applied a "stopping" force over a distance) in order to change its kinetic energy.

Yes this happens and it happens because when an airplane lands it displaces air around it with a high pressure and speed.This large volume of displaced air with high speed exerts a high pressure on the car and it flies away from the track

Fly eyes work like fantastic motion dectectors. Their sight system is completely different for a very different reason. Detecting motion not specific visual acuity

I would use a string attached to the metal arm on the trap and wind the other end of the spring arouhd the axle of the car.wind the string tight around the axle with the trap open.  When you release the trap, it should drive the wheel by spinning the axle.  Have fun!

They can go anywhere they won't get wet. This includes places like the bark and leaves of trees, porches, grass, or anywhere else. But I suspect many just die, and it is the babies that live on. Flies don't live very long anyways, and the larva grow up fast. If a generation of flies die, the next will be around in a little bit.

I'm not sure what you mean, but you can wreck a car at any speed. My car doesn't even go to 100 miles per hour.

OK, I'll try to help you learn the principle so you can pass the test. My explanations are in ().\n\nA high tech jet car speeds along the desert floor at a constant velocity of 180 miles/hr north.a) what is the net force on the jet car? the jet car hits some sand which causes a drag force on the car of 5000 N to the south. The computer instantly compensates so the jet exerts a thrust force on the car of exactly 5000 N to the north at the same time the car hits the sand. The jet car now... choose ALL that apply: \n\n(There has been drag all along. Since the car has been going at a constant velocity, the car's jet has to be exerting an equal and opposite force to compensate for the drag. If the drag and thrust are equal and opposite there's no net force. Newton's 1st says it will stay in motion at the same speed in the absence of a net force. So now, the net force = 5000 N - 5000 N = 0.) The car \n\nmaintains constant velocity\nmoves with constant non-zero velocity\n\n(I explained all this above.)\nNewton's first law states: When the __ net force__ on an object is zero, the object will __maintain__ constant __velocity__.\nAnother way of saying this is that, if the total force on it equals zero, an object's _acceleration__ will also be zero.\n\nIs it necessary to apply a force to keep an object going in a circle at constant speed? \n\n(The object will want to keep going at constant speed in a straight line because of inertia - without a net force it will do that. The force required to go in a circle is towards the center.)\n\nYes, because the __velocity__ is changing.

UNFORTUNATELY IT WORKS, IS DIRECTLY CONNECTED WITH A SPEED SENSOR CONNECT TO THE OFFICER'S VEHICLE.  IT WORKS APPROACHING OR ON-COMING.  ANTENNA'S ON VEHICLES ARE DIFFERENT BUT DOWN HERE WE USE A ANTENNA WHICH APPEARS TO BE A SPOTLIGHT HOOKED OVER THE TOP OF THE WINDOW GLASS.  IT MAY BE AIMED UP OR DOWN THE ROAD.\n\nWORKS AS LONG AS THE VEHICLE IS IN SIGHT!\n\nDRIVE CAREFUL HEAR !
