Hello, according to the classic physics a body subjected to an acceleration must dispers energy, the Earth is subjected to a centripetal and centrifugal force so why it doesn't stop to turn ?
So why the Earth radius shoud decrease 1 femtometer per day ?mfb said:However, if you consider masses in the solar system: No. It involves a loss of energy.
They do not have a perfect radial symmetry.How can gravitational waves compensate for this loss of angular momentum if they're directed radially outwards?
Earth doesn't stop turning because of its inertia and the force of gravity. Just like a spinning top, Earth's rotation creates a force that keeps it spinning.
No, Earth is expected to keep rotating for billions of years. Its rotation is caused by the conservation of angular momentum, which is a fundamental law of physics.
If Earth suddenly stopped turning, its atmosphere and oceans would keep moving at the same speed, causing catastrophic winds and tsunamis. The change in rotation would also affect Earth's climate and weather patterns.
Humans do not have enough force or technology to significantly affect Earth's rotation. However, some scientists believe that climate change may be causing Earth's rotation to slightly slow down.
Earth's rotation is what causes day and night, and also influences the movement of air and ocean currents, which in turn affects our weather. Our bodies have also evolved to adapt to Earth's rotation, making it an important factor in our circadian rhythms and sleep patterns.
