Question

1. Briefly explain rotation and revolution.​

Answer 1

Here is your answer

Explanation:

ROTATION:

A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axis. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation around an external point, e.g. the planet Earth around the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. The axis is called a pole.

REVOLUTION:

Revolution (Latin: revolutio, "a turn around") is a fundamental and relatively sudden change in political power and political organization which occurs when the population revolts against the government, typically due to perceived oppression (political, social, economic) or political incompetence. In book V of the Politics, the Ancient Greek philosopher Aristotle (384–322 BC) described two types of political revolution.

Answer 2

$\huge \mathbb \blue{ANSWER}$

$\mathfrak \orange{Rotation}$

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.

EXAMPLE

• The earth's orbit around the sun.

• Agroup of people holding hands in a circle and walking in the same direction.

CHARACTERS OF ROTATION

• The earth's rotation axis is always inclined to its orbital plane at an angle of 66 and a half degree.

• The earth rotation causes day and night.

_______________

$\mathfrak \orange{Revolution}$

Revolution is the movement of one object around a center or another object, a forceful overthrow of a government by the people or any sudden or grand change.

EXAMPLE

An example of revolution is movement of the earth around the sun.

Why is Earth's revolution important?

The revolution of the Earth on its axis is important in setting up the seasons. .The direction of Earth's revolution is in the direction of its rotation. Because the path around the sun is not circular, we are closer to the sun at certain time .
