FAQs on Quick Revision: Gravitation - Physics for JAMB

1. What is gravitation?
Ans. Gravitation is the natural phenomenon by which all physical bodies are attracted to each other. It is the force that governs the motion of planets, stars, and other celestial bodies in the universe.
2. Who discovered the concept of gravitation?
Ans. The concept of gravitation was discovered by Sir Isaac Newton in the late 17th century. He formulated the laws of motion and universal gravitation, revolutionizing the understanding of the physical world.
3. How does gravitation affect the motion of objects?
Ans. Gravitation affects the motion of objects by exerting a force of attraction between them. This force, known as gravity, pulls objects towards each other, causing them to move in specific paths such as orbits around larger bodies.
4. Can gravitation act over long distances?
Ans. Yes, gravitation can act over long distances. According to Newton's law of universal gravitation, the force of gravity between two objects decreases with the square of the distance between them. However, it never completely disappears, allowing the influence of gravity to extend across enormous distances in space.
5. How does the mass of an object affect the force of gravitation?
Ans. The mass of an object directly affects the force of gravitation. According to Newton's law of universal gravitation, the force of gravity between two objects is directly proportional to the product of their masses. Therefore, an increase in the mass of an object will result in a stronger gravitational force between that object and other bodies.
