i remember walking in seeing just the video part of the original news story and immediately laughed after saying "Ha magnetic children." and my mom just looked at me like.
I think so as everything would suddenly move in one direction -the earth so buildings would collapse if not just disintegrate due to the sudden acceleration
But its not really acceleration. You were already moving that speed and so was the planet but because it became stationary, you would go flying. Its the same as with a car when you stop really fast.
My mistake ya you make a good point. Under newtons first law of motion that object would stay in motion unless acted on by another unbalanced force (eg. friction) So they would just topple over. Thanks for pointing out the mistake in my comment.
the magnetic poles? i think you mean the geographical poles.
and to answer the question, No! your angular momentum is way to low. the earth spins with a frequency of 0.0000116 hertz.. (86164 seconds for a rotation) .. thats not very rapidly
the earths mass is 5.97219 × 10^24 kilograms. and you need to have the centripetal force of the earth or some **** (got it off the internet so dont think im smart enough to figure this out) multiplying it would result in the force required to stop it from spinning being 9.9577042267626e+21kg
So... 1.79208 x 10^23 Newtons of force would be needed at the exact opposite vector the Earth is spinning in.
-----------------------------------------
1 N is 0.1225 lbs so you would need a force of 21,952,980,000,000,000,000,000 pounds.
Almost.
This problem requires rotational mechanics, i.e. mass is replaced with moment of inertia, force by moment and momentum but angular momentum. Besides, stopping linear movement by applying a force also requires time.
But to the question at point:
Earth's mass: me=5,97e24 kg
Earth's radius: R=6,38e6 m
Moment of inertia: K=(2/5)*Me*R^2=9,72e37 kgm^2 AeB means A*10^B Now we need the moment, which is force F multiplied by R: M=F*R (note: M=/=m_e)
BUT: in relation to Newton's 2nd: M=dL/dt, in which dL=change of angular momentum L; dt=change of time. Angular momentum L=w*K, in which w=2*pi*f and f is Earth's spinning frequency (once every 24h)-> w=pi/43200 1/s
We get F*R=dL/dt -> F=dL/(r*dt) dL=-9,72e37*(pi/42300) 1/s =-7,07e33 We can forget the minus sign since we aren't calculating vectors. Let's make an assumption: we want to stop Earth in exactly 1 second -> dt=1s -> F=7,07e33/6,78e6=1,043e27 Newtons for 1 second at the equator stops the Earth's spinning.
