How To Stop The Spins When Drunk Domain_10
What would happen if World suddenly stopped spinning?
Earth is steadily spinning like a top, fifty-fifty if we tin't see, touch, hear or experience information technology. And then, what would happen if Earth were to abruptly stop rotating?
If the spinning were to cease, the athwart momentum of every object on Earth would rip the surface apart, resulting in a really, really bad day.
"This is just a thought experiment," said James Zimbelman, senior geologist emeritus at the Smithsonian's National Air and Space Museum in Washington, D.C. "There is no natural forcefulness that would stop the Earth from spinning. That is role of why the planet has been spinning since information technology formed, which is pretty impressive."

Put a spin on it
Earth makes i consummate rotation on its axis every 23 hours, 56 minutes and 4.09053 seconds. This translates to land at the equator moving at virtually 1,100 mph (1,770 km/h), with rotational velocity decreasing to nothing at the poles, according to Zimbelman. If the planet were to come to an sharp halt, the angular momentum imparted to the air, water and even rocks along the equator would keep moving at this speed of i,100 mph. The movement would scour the surface while ripping it apart and sending shards into the upper regions of the atmosphere and outer space.
But what is athwart momentum?
Allow's take a step dorsum. Linear momentum is the product of an object's mass and its velocity (direction and speed). A rider in a moving car that stops abruptly will go on to move forrad due to linear momentum. Ouch.
Athwart momentum is a rotational analog to linear momentum. Information technology is the production of the moment of inertia (the rotational forcefulness needed to rotate mass) and angular velocity. A quarterback imparts athwart momentum to a football every bit information technology is heft through the air toward the wide receiver.
"One of the fundamentals of physics is the conservation of athwart momentum," Zimbelman told Alive Science. "In one case something is spinning, y'all have to exert the same strength [in the opposite direction] to stop it from spinning."
But all would non be not lost if the Earth were to stop spinning.
Regroup, reform, accrete
According to Zimbelman, the bits and pieces that broke away from the surface would regain some spin every bit Earth and its remnants continued on their path effectually the sun. Somewhen, the planet's gravitational pull would draw the halo of fragments back with an unexpected effect.
"What [Isaac] Newton helped us figure out with classical mechanics is that the pieces accumulating and moving closer together would release some of their own free energy, heating things up," Zimbelman said.
Call back of it like a meteorite streaking across the heaven. The remnants that ended up in the far reaches of the atmosphere and outer space would be fatigued to the surface past the planet's gravitational pull, and they would release energy upon impact. The constant battery of these bits and pieces would liquefy the chaff into a molten "body of water of rock," Zimbelman said. Eventually, colliding fragments would be reabsorbed into the molten sea through a process chosen accretion.
According to Zimbelman, the rapid and destructive transition would too vaporize most of the water on the planet's surface. While most of this vaporized water would be lost, some might be incorporated into newly solidified minerals, like olivine. Finally, not all of the fragments would be reabsorbed through accretion. Some of the planetary bits would exist swept up by the moon'south gravitational pull, bombarding the nearby satellite and creating countless more craters across its surface.
