Why earth does not fall towards sun due to its attrraction?

Text Solution

AI Generated Solution

To understand why the Earth does not fall towards the Sun despite the gravitational attraction between them, we can break down the explanation into several steps: ### Step 1: Understanding Gravitational Attraction The Earth and the Sun exert a gravitational force on each other due to their masses. This force is described by Newton's law of universal gravitation, which states that every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. ### Step 2: The Concept of Centripetal Force In the case of the Earth orbiting the Sun, the gravitational force acts as a centripetal force. A centripetal force is necessary for any object to move in a circular path. It acts towards the center of the circular path, which, in this case, is the Sun. ...
