What physical laws prevent my f.a. from performing this feat?

It's really quite simple, Newtons law states that and object in motion will remain in motion until acted on by an out side source also and object at rest will remain at rest until acted upon by an outside source. So with that you are moving at 50 mph on top of a car and you already have 1 factor working on you to keep you in motion and 2 trying to stop you. The movement of the car is providing thrust while the wind resistance and gravity are trying to slow you down now when you jump you have removed your thrust. now remember and object in motion will remain in motion until acted on well now the wind will marginally slow you down while gravity yanks back to earth and finally the unforgiving pavement will prove Newtons Law when your FA is smeared all over the highway
but please try and make sure to tape it I would love to see lol

The biggest difficulty would be the wind resistance. Remember that the car is continually being powered to overcome various types of resistance such as rolling resistance and wind resistance. Once you jump off the car, you will start to decelerate from the wind resistance and it is possible (if you jump high or from the back of the car or the car is moving fast, which would increasing your wind resistance) that you will come down behind the car. There are other factors such as the car's vibration and changes in elevation and lack of firm, level landing place which will make landing cleanly tricky and car turns that will take the car out from under you. Now just think, if you were in a large semi trailer and you jumped up, then assuming the truck has not turned, you would land very near from where you jumped. This is because the air in the trailer is moving at the same speed as you and the truck and does not slow you down.

You can, but only if you are able to jump up faster or AS fast as the car is moving. If a car is going 60mph then your legs need to be able
compleletley clear the surface of the car at 60mph or greater or the
car will pull your legs forward and force you to fall backwards. If the car is moving slow enough you could do it but then again you probably would just land on the back of the car by the time gravity pulled you down versus how far the car actually moved.
(this is assuming there is zero wind)

Your body is in motion at the SAME SPEED as the car.
so if you jump up the wind resistance of your body slows you down just enough that the car leaves you,.
And bang!! You smash your face into the ground.
IF there was no wind resistance when you came down you would
land almost where you were on the top of the car.
A good example of this theory is do it on top of a moving train.
When you jump up and come back down you land in a different
spot on the railroad car. but since it is like 60 feet long
you still land on it.

How fast are you going?
If air resistance isn't a factor, then you can. I would take into account the force that is applied to your body by the air that you are moving through. Otherwise, you will probably hurt something by falling off a moving car.
Same thing with jumping up and down on a train. It is inertial frame of reference, no forces acting on you except gravity.

verify the voltage regulator, you additionally can use a modern-day tester to verify if something would are turning out to be fried, like the starter or voltage regulator or the computing device. as nicely the fuses on your dashboard or on the interior someplace there additionally must be some fuses decrease than the hood as nicely. in case you dont locate the subject by then i could in all probability merely pay for a diagnostic attempt beings you sound robotically vulnerable and ought to repair the subject your self once you get the prognosis. mechanics are costly by the hour. and that i ll wager you will detect some cupons for a diagnostic attempt in those unfastened books at each and all of the convienant shops. solid success!

Because your body would still be moving with the trajectory of the car, just because you jump up doesn't mean that the energy and the direction of the car that your on top of stops! I can't remember what it's called but it has a scientific name...I'm thinking kinetic energy?!

you are moving as fast as the car...same with earth. jump up and when you come down you are on the same spot..imagine if this did not happen move against the spin of the earth you would really have a hard time going forward

shelsi has it. In a vacuum, you could do that.
Edit: What I mean is, you could jump straight up and land back on top of the car, assuming it hadn't turned, sped up or slowed down.

friction, wind, moving energy, u shoodnt try it cuz ud get run ova, id recomend trying it on a plane
