Question

Ratation of the Earth on its axis is the example of which type of motion

Answer 1

Rotation of the Earth on its axis is the example of periodic motion:

• The earth's rotation around its axis is periodic because it occurs at regular intervals.
• The rotation of the earth around a fixed point is not a to and fro type of motion, so its motion is not (Simple Harmonic Motion) SHM.

Hence, answer to the above question will be periodic motion.

Answer 2

The rotation of the Earth on its axis is an example of centripetal motion.

• Centripetal motion is the force for circular motion since it is towards the center of the circle.
• The rotation of the earth creates a centripetal force to its gravity, this is the reason it bulges slightly around the equator.
• The earth does not rotate in circular motion its rotation is called orbiting.
• The earth rotates at 1000 km per hour there is a centripetal force on everything on the surface.
