What is rotation
  • 1 answers

Meghna Thapar 5 years, 3 months ago

A rotation is a circular movement of an object around a centre of rotation. If three-dimensional objects like earth, moon and other planets always rotate around an imaginary line, it is called a rotation axis. The axis passes through the body's centre of mass, the body is said to rotate upon itself or spin. Earth's rotation is the rotation of Planet Earth around its own axis. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise. ... The South Pole is the other point where Earth's axis of rotation intersects its surface, in Antarctica.
