Question

speed of earth is an example of movement of force​

Answer 1

Earth's rotation or spin 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.

Answer 2

Answer:

The correct answer is relative momentum. The speed of earth is an example of relative momentum.

Explanation:

• Relative momentum is the same force that propels the planets and the rest of the solar system into rotation around the sun.
• Gravity drew everything together when it was only dust and pieces of stuff whirling around on their own.
• But when two pieces of matter are drawn together, they won't just come to rest together because each piece must cope with relative inertia.
• As a result, as they grow closer, they enter orbits around one another, and when they ultimately stick together, their velocity is converted into spin.
• The centre of gravitational attraction between two objects, or their barycenter, is nearly never exterior to their mass, and instead, they orbit one another instead of colliding exactly dead on and exchanging their lost velocity as heat.

• As a result, there is an accumulation of small spinning clumps that are gradually squeezed together by the growing mass of all the nearby clumps that coalesce in the same orbiting/spinning way, until you finally have large spinning clumps that are held tightly together by the gravity of their own masses, all of which are spinning around the largest clump in the area—the central star.

• In the same way that the dust from stars swirls around in galaxies, the Earth rotates because it was once a cloud of dust around itself.
• As its mass rose, the dust clumped together and accumulated more and more debris.
• The total momentum of all the small pieces of matter that came together to form the Earth is represented by the angular momentum of the planet.
• When something is moving, it essentially stays moving. The momentum is maintained.
