If the Earth's rotation causes centrifugal force, pushing us away from it and decreasing our weight, how much more would we weigh if this centrifugal force were not present?

...what speed are the tires travelling at the contact point with the road? Please explain your reasoning.

If two cars leave the same house at the same time, they will be traveling along on two roads to get to their destination, the first road, has a speed limit of 15mph, and it is 1/4 of the overall distance to their destination, the second road has a speed limit of 45mph, and it covers the remaining 3/4 of the distance.

now, Car A stops for gas halfway during the 1st leg of the trip (during the 15mph zone), while Car B continues on. after a Time Gap A, Car A continues on its path. Currently trailing Car B

Car B then stops for gas halfway through the 2nd leg (the 45mph zone) and stops for the same amount of time (Time Gap A), after continuing on its journey, both Car A and Car B arrive at their destination.

The question is, do they arrive at the same time? and if not, who wins? and if you can, why exactly?

friction has to do with traction, and obviously, a drag racer with big back wheels desires traction, but if you look at the friction formula, no where in the formula does it require the surface area or any area at all, so why is a dragrace car's tires so much bigger than normal?

Gentlemen.
I have only two questions:
First -
Hasn,t my parrot flown to you?
Second -
Why does everyone says,
that the relative movement is only real: v=s/t,
if the speed of quantum of light is absolute: c=1 and
it can occur only in absolute space: Vacuum T=0 ?
P.S.
You can easily find out my parrot,
it has learned only two sentences:
“there is no absolute movement’,
“ there is no absolute reference system”.

If protons and electrons experience mass defect in atomic structures than the size and mass of the atomic elements in the peirodic table are not the same mass. Hence, Electron mass is not constant depending on which structures its trapped in?So how is mass structure calculated?

Escpe velocity = root(2GM/R)
so theoritaclly for it to be very high, mass of the black hole should be very high and radius very small
Hows that possible?

People say that ......when friction is undergone.....somewhat is used as Mechanical Energy,,,,,other decipated as "Joules Heat"....thats totally fine BUT WHERE DOES THE HEAT DISSIPATED GO???????...well...we can say it goes into the atmosphere..but WHERE into the atmosphere......some perculation point??....some point where this energy gets used up in some form of evaporation of water.....or even Fission??? ..plz si need help
