Rotation and Revolution. While rotation means spinning around its own axis, revolution means moving around another object. Taking the example of the Earth, which rotates 366 times to complete one revolution around the Sun.
What is Rotation?
An object moving around itself in its own axis is called Rotation
Eg: Planet Earth rotating itself
What is Revolution?
Any object moving in a circular motion around a center (or something) in orbit is called Revolution
Eg: Earth rotating around the sun.
Rotation and Revolution of Planets:
|PLANET||ROTATION PERIOD||REVOLUTION PERIOD|
|Venus||224.7 days||243 days|
|Earth||365.2 days||23hrs 56mins 4 secs|
|Mars||687 days||24hrs 37 mins|
|Jupiter||11.86 years||9hrs 55mins 30 secs|
|Saturn||29.46 years||10hrs 40mins 24 secs|
|Uranus||84 years||16hrs 8 mins|
|Neptune||165 years||16hrs 11mins|
Differences between Rotation and Revolution:
|A circular motion around an axis, within the body of any object, is called rotation.||A circular motion around an axis, located outside and around the object, is called a revolution.|
|Rotation is the movement of an object in its own axis||revolution is the complete movement around something, i.e. an object or center.|
|Rotation is when the object that spins around an internal axis||revolution is when the object travels around an external axis.|
|In rotation, the object moves without changing its position||In revolution, the object moves along with a continuous change in its position.|
|.Earth’s rotation is from the west towards the east, which it completes in approx. 24 hours||the revolution of the Earth around the Sun is in anti-clockwise manner i.e. west to east., which is completed in around, 365 days.|
|Examples of rotation are the hands of clocks, spinning top, etc.||Examples of revolution are rounding a curve in a car, kids merry go round, etc.|
Therefore, with the above discussion, you may get ample knowledge about the two terms. While rotation means spinning around its own axis, revolution means moving around another object. Taking the example of the Earth, which rotates 366 times to complete one revolution around the Sun.
