What is the difference between rotation and revolution?
Answer:
Rotation and revolution are two different motions in astronomy and physics.
Rotation:
- Rotation refers to an object spinning around an internal axis.
- For example, the Earth rotates on its axis, causing day and night.
- The rotation of an object is usually measured in degrees per unit of time.
Revolution:
- Revolution refers to an object moving around an external axis.
- For example, the Earth revolves around the Sun, creating the change of seasons.
- The revolution of an object is generally measured in units of time, such as days or years.
In summary, rotation is an internal spinning motion of an object on its axis, while revolution is an external motion of an object around an external axis or another object.
