What energy that makes the earth to rotate at its axis?
An object that rotates has the tendency to continue rotating. There is no need for a continuous energy supply. In this case, the rotational energy was there from the moment that Earth formed. - Actually, to be precise, at first there was much more rotational energy; Earth's rotation has been slowing down due to tidal forces. It will continue slowing down until Earth always shows the same side to the Moon.
How long do the two movements of the earth last?
The Solar System is about 4.6 billion years old; the Earth formed around that time, and has been orbiting the Sun, and rotating, since then.Note that Earth's rotation has been slowing down over time, due to tidal forces, mainly from the Moon.
Would the earth spin faster or slower if their was no moon?
Probably faster: The Moon has been slowing down Earth's rotation for quite a while.
How does speed affect friction?
That depends on the exact circumstances. Solid friction hardly depends on the speed at all. In fluid friction, the situation is more complicated. Usually there is some range of speeds for which friction is more or less proportional to speed; at higher speeds, the force of friction may even become proportional to the square of the speed.
Why and how was the length of the day just Eighteen to Nineteen hours per day in the previous geological ages?
The moon is effecting the Earth via tides. Over million of years the friction of the oceans and the Earth is slowing down its rotation causing the length of the day to increase. Eventually the Earth will have the same length of day and month, but that would be hundreds of millions of years from now.
When a body is in motion on earth there is always what to aid in slowing it down?
Friction.
What force is responsible for the slowing down?
Friction is a force that will slow things down.
What is the reaction of the car slowing down?
sTOPPING IT OR FRICTION!
What causes the earth to slow down its orbit?
Tidal forces between the Sun and the Earth cause friction in Earth's surface - sort of a rippling - that slows the orbit. It is easier to see these tidal forces acting on the water in our oceans than it is to see in our land, but they are there.
The interaction between the tides and the moon is causing the rotation of the earth to?
It slow down the rotation of the earth due to friction of water motion acting on to earth surface. The earth spin is slowing down by about 1.5-2 milliseconds per century.
When is friction useful when ice skating?
for slowing down, stopping etc
How does friction and gravity affect skateboarding?
By slowing it down or speeding it up.
How does the force of friction affect a slipping shoe?
By slowing down the shoe.
When do you need to increase friction?
We Increase Friction when we are stopping a car, bike or when slowing down to a way up.
Does earth change the speed of its spining?
No, the speed of Earth's rotation remains relatively constant. However, there are factors such as tidal friction and atmospheric wind patterns that can cause very small fluctuations in the length of a day over long periods of time. These fluctuations are not noticeable to us in our daily lives.

Can earths revolution generate electricity?
Well, not directly, since there is nothing "against" which Earth is rotating; nothing where you can hold on to, to slow Earth down. Of course you can't get energy without slowing Earth down, since that would violate Conservation of Energy. And just slowing down Earth by itself, without affecting other objects in the Universe, would violate Conservation of Rotational Momentum. However, the tidal energy is indirectly a result of Earth's revolution.
