From where does earth get energy for rotation?

This is due to Newton's first law and conservation of energy. In summary, the Earth does not need any energy input to rotate, as it is not doing work against the sun. This is due to Newton's first law and conservation of energy.

from where does Earth get energy for rotation?as its rotating means its doing some motion to work again sun's gravity soo from where does Earth gets this energy?

No, the Earth is not doing work against the sun, so no input is required.

but anyhow how Earth gets energy for rotation?

Like I said, no energy input is required. That is due to Newton's first law and conservation of energy.

google... "why do planets rotate"

And once they "start" they don't need energy, as Russ explained.

Once something is rotating, it doesn't need energy to keep on rotating. In fact, it needs energy to STOP it from rotating.
 

1. What is the source of energy for Earth's rotation?

The source of energy for Earth's rotation is primarily the Sun. The Sun's gravitational pull on Earth's tilted axis causes the planet to rotate on its axis, creating the day and night cycle.

2. How does the Sun's energy contribute to Earth's rotation?

The Sun's energy is transferred to Earth through radiation, which is then converted to heat. This heat causes the atmosphere and oceans to circulate, creating wind and ocean currents that also contribute to Earth's rotation.

3. Does Earth's rotation affect its climate?

Yes, Earth's rotation plays a crucial role in regulating its climate. The rotation affects the distribution of sunlight and heat, which in turn affects wind patterns, ocean currents, and weather patterns.

4. Can changes in Earth's rotation affect life on the planet?

Yes, changes in Earth's rotation can have significant impacts on life on the planet. For example, changes in the tilt of Earth's axis can alter the amount of sunlight and heat received by different regions, leading to changes in climate and potentially affecting ecosystems and species' survival.

5. Will Earth's rotation ever stop?

No, Earth's rotation is expected to continue as long as the Sun continues to provide energy. However, factors such as tidal forces from the Moon and other celestial bodies, as well as changes in the Earth's mass distribution, can cause slight variations in the speed of rotation over time.
