FAQs on Gravitation Video Lecture - General Awareness for SSC CGL

1. What is the formula for gravitational force?
Ans. The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two objects.
2. How does the mass of an object affect the gravitational force acting on it?
Ans. The gravitational force acting on an object is directly proportional to its mass. This means that the greater the mass of an object, the greater the gravitational force acting on it.
3. What is the difference between weight and mass in the context of gravitation?
Ans. Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity. Mass remains constant regardless of the location, but weight can vary depending on the gravitational acceleration at different locations.
4. How does the distance between two objects affect the gravitational force between them?
Ans. The gravitational force between two objects is inversely proportional to the square of the distance between their centers. This means that the greater the distance between two objects, the weaker the gravitational force acting between them.
5. Can gravitational force be negative?
Ans. Gravitational force is always attractive and therefore cannot be negative. It is a force of attraction between two objects with mass.
