| 1. What is gravitation? |  |
Ans. Gravitation is the force of attraction that exists between any two objects with mass. It is responsible for keeping planets in their orbits around the sun and objects on Earth's surface.
| 2. How does the force of gravitation work? | |
Ans. The force of gravitation works based on the principle that every mass in the universe attracts every other mass. The magnitude of this force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
| 3. What is the universal law of gravitation? | |
Ans. The universal law of gravitation states that every particle 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 their centers.
| 4. How is the weight of an object related to gravitation? | |
Ans. Weight is the force exerted by gravity on an object. It is directly proportional to the mass of the object. The weight of an object can be calculated using the formula: weight = mass × acceleration due to gravity.
| 5. What are the factors that affect the force of gravitation? | |
Ans. The force of gravitation is affected by two main factors: the masses of the objects involved and the distance between their centers. As the masses increase, the force of gravitation also increases. However, as the distance between the objects increases, the force of gravitation decreases.
