you think a brick wall can stop a moving object at 1600kph?

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.

how much energy would there be needed to stop something as big as our planet from spinning?

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

Assuming you mean spinning, and not orbiting...

Newtons second law of motion is Force = (Mass)(Acceleration). F=MA.

Earths mass is roughly 5.9736 × 10^24 kg (according to Google).

The Earths acceleration is 0.03 m/s2 (soruce at tinyurl.com/fjscience).

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.

Physics gets a lot more ****** up if stuff is rotating.

Plus, you calculated the force that would be required to stop the earth from accelerating, not stoping it.

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)*M
e*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.

Physics undergrad out.

Implying I need the earth to stop spinning to jerk sideways at 1,600 km/h.

Both you and the earth are moving; if the earth suddenly stops you're going to simply just start flying at stupidly high speeds if you had jumped instead of jerking

If you will die either way jumping sounds like more fun.

with your logic, If I jumped right now, everything would move past me, cause i'm not moving with the earth since I'm not on it, but here is the thing, we are already accelerating sideways, and jumping would not relive that acceleration, in which case, we keep up with everything as we jump, (not to mention gravity also locking us in place), so if the Earth stopped, our acceleration wouldn't be effected by earth stopping if we are in the air, so we would just go flying in an incredible speed, prob faster than those who where still on the ground. As for those of us on the ground, inertia which makes objects keep trying to move when they are moving, would force us to fly off into the direction earth was spinning.

well, no

just near the equator.. the closer you are to the poles, the less powerful the inertia is.

well if you stand exactly on one of the earths magnetic poles, will you just spin rapidly for a couple of seconds, or just fall over?

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
