## FAQs on Gravitation Video Lecture - Crash Course: Class 9 (Hinglish)

 1. What is the concept of gravitation?
Ans. Gravitation is the force of attraction between two objects with mass. It is responsible for the phenomenon of weight and keeps the planets in their orbits around the sun.
 2. What is the difference between mass and weight?
Ans. Mass is the amount of matter present in an object, while weight is the force exerted on an object due to gravity. Mass is measured in kilograms, while weight is measured in newtons.
 3. What is the universal law of gravitation?
Ans. The universal law of gravitation states that every object in the universe attracts every other object 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.
 4. How does the force of gravity change with distance?
Ans. According to the universal law of gravitation, the force of gravity decreases as the distance between two objects increases. It follows an inverse square relationship, meaning that if the distance is doubled, the force of gravity becomes one-fourth of its original value.
 5. What are some applications of the concept of gravitation?
Ans. The concept of gravitation is applied in various fields, such as astronomy, space exploration, and engineering. It helps in understanding the motion of celestial bodies, calculating the trajectories of spacecraft, and designing structures like bridges and buildings to withstand gravitational forces.
