Today while I am travelling from Chennai to Vellore in bus, I don't find seats in bus so I decided to travel in bus by standing....

While moving, the bus driver suddenly applied brake....And obviously I am forced to move forward from my original position.
Have you ever think why you are forced to move forward??
It is because the brake is applied only to the bus and not to us...
We are travelling along with the bus at some speed..If suddenly brake is applied we are forced to move at the speed of the bus...
Let us come to the topic..What if earth suddenly stops spinning ???
Earth spins at 1698.21222 km/hr. And we cannot feel it because we are travelling along with the earth at constant speed.
To know about this we should know why our planet rotates !
We all know about Newton 1st Law of motion that Law of Inertia..
i.e., Object in motion tends to motion unless an external force is applied
The Earth spins because it formed in the accretion disk of a cloud of hydrogen that collapsed down from mutual gravity & it continues to spin because of Inertia.
But there is some force of friction that tends to stop earth-bound objects moving forever.
But for the earth rotating on axis there is no strong enough counteract force working to slow down earth. (Except tidal effect of the moon)
Because of the moon, the spin of the earth is slowing down at a rate of about 1 milli-second year.
Today it took 23 hrs 56 min for 1 revolution.
At the time of Dinosaurs days its 22 hrs.
Million's of years from now the cycle of a day on earth will likely stretch to 25 or 26 hrs.
When our Earth touches 40,009.88 hrs to complete its one revolution, then the speed will nullify i.e., 0 km/hr.
Note :- The circumference of the earth is 40,009.88 km.
Distance / Time = Speed
40,009.88 / 23.59= 1698.2122 Km/hr ( Current Speed )
So, it will took many many trillion of years to stop its spinning, so the process is very very slow, since the process is slow and not sudden it wont affect in future also.
But the day and night time will increase every million years.

Earth spins at 1698.21222 km/hr. And we cannot feel it because we are travelling along with the earth at constant speed.
If Earth stop rotating.,
- All buildings, rocks, living beings, top soil, trees will thrown out to Atmosphere at 1698 km/hr.
- 1/2 year Day light, 1/2 year Night time.

THIS VIDEO SHOWS HOW THE EARTH IS FORMED AND WHY IT ROTATES ??
