## FAQs on Mindmap: Gravitation - Physics Class 11 - NEET

 1. What is gravitation?
Ans. Gravitation is a natural phenomenon by which all objects with mass or energy are brought toward one another. It is the force that attracts objects towards the center of the Earth and keeps planets in orbit around the sun.
 2. What causes gravitation?
Ans. Gravitation is caused by the presence of mass or energy. According to the theory of general relativity, mass and energy curve the fabric of spacetime, creating a gravitational field that influences the motion of other objects.
 3. How does gravitation affect the motion of objects?
Ans. Gravitation affects the motion of objects by exerting a force on them. This force, known as the gravitational force, pulls objects towards each other. The strength of the force depends on the masses of the objects and the distance between them.
 4. What is the law of universal gravitation?
Ans. The law of universal gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
 5. How does gravitation explain the motion of planets?
Ans. Gravitation explains the motion of planets by the concept of orbital motion. According to this concept, planets orbit around the sun due to the gravitational force exerted by the sun. This force acts as a centripetal force, keeping the planets in their elliptical orbits.
