FAQs on Gravitation in One Shot (NCERT) Video Lecture - Physics Class 11 - NEET

1. What is gravitation?
Ans. Gravitation is the force of attraction between any two objects with mass. It is responsible for keeping planets in orbit around the sun, objects falling to the ground, and many other phenomena in the universe.
2. How does gravitation work?
Ans. Gravitation works based on the principle that any two objects with mass will attract each other 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.
3. What is the importance of studying gravitation?
Ans. Studying gravitation is essential as it helps us understand and explain various natural phenomena, such as the motion of planets, the tides, and the behavior of objects in free fall. It also forms the basis for understanding the principles of celestial mechanics and the structure of the universe.
4. How does the mass of an object affect the force of gravity acting on it?
Ans. The force of gravity acting on an object increases with its mass. In other words, the more massive an object is, the stronger the gravitational force it experiences.
5. What is the difference between weight and mass?
Ans. Weight is a measure of the force of gravity acting on an object, while mass is a measure of the amount of matter in an object. Weight varies with the strength of the gravitational field, while mass remains the same regardless of the gravitational field.
