WitrynaThe absolute centre of a spinning object is stationary, but the way in which speed increases with distance from the centre depends on the nature of the object. For rigid objects like snooker balls, the speed of spinning - that is, the number of degrees moved through each second - is constant right through. But for fluid objects such as the Sun ... WitrynaActually, I'm sure the object which crashed into the earth and created the moon changed the earth's angular rotation, but since then it has been constant. Angular momentum is conserved, and here the energy that goes with it is conserved too, so the earth spins happily on and on. David Schmid (published on 05/30/2013)

WitrynaBy re-writing the first equation, we can calculate the speed at which the collision occurs: V f = V 0 2 − 2 a d = 8.2 m e t r e s p e r s e c o n d. (where d = 40 metres minus the reaction distance of 27.1 metres = 12.9 metres). Thus, the impact occurs at about 30 kilometres/hour, probably fast enough to kill Sam.

WitrynaThis pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles.
