If everything jerks, did anything really jerk?
#35 to #21 - tugaii (07/05/2013) [-]
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
User avatar #40 to #35 - volshimond (07/05/2013) [-]
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.
#53 to #40 - anon (07/05/2013) [-]
objects with lesser mass would 'jerk' further than objects of a greater mass, they wouldn't move in sync with each other.
#264 to #40 - tugaii (07/06/2013) [-]
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.
User avatar #25 - theangryvegan (07/05/2013) [-]
well, no

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

User avatar #81 to #25 - ktbmnf (07/05/2013) [-]
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?
User avatar #92 to #81 - theangryvegan (07/05/2013) [-]
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
User avatar #239 to #92 - ktbmnf (07/05/2013) [-]
ah, yeah. geometrical, magnetic, same thing :p

thanks for clearly that up though! +1 for you

how much energy would there be needed to stop something as big as our planet from spinning?
#103 to #91 - McCockAFucker (07/05/2013) [-]
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
#111 to #91 - mralice (07/05/2013) [-]
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.
#243 to #111 - anon (07/05/2013) [-]
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.

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.

more destructive would be the asteroid that hit the earth with enough force and at an appropriate angel to make it stop spinning

User avatar #33 to #31 - TheMather ONLINE (07/05/2013) [-]
Wouldn't have to hit it, a barrage of large enough asteroids passing next to it could stop the rotation through their gravitational pull.
User avatar #50 to #31 - lateday (07/05/2013) [-]
Just for the sake of it, it just suddenly stopped. It's hypothetical.
