FAQs on Gravitation Video Lecture - Science Class 9
| 1. What is gravitation? |  |
Ans. Gravitation is the natural force of attraction between any two objects with mass. It is responsible for the phenomenon of weight and keeps planets, stars, and other celestial bodies in their orbits.
| 2. How does gravitation work? | |
Ans. Gravitation works based on the principle that any two objects with mass will attract each other. The force of gravity between two objects depends on their masses and the distance between them. The larger the mass of an object, the stronger its gravitational pull.
| 3. What is the significance of gravitation in our daily lives? | |
Ans. Gravitation plays a crucial role in our daily lives. It keeps us grounded on Earth, ensures the proper functioning of machinery and vehicles, and allows objects to fall towards the ground. Additionally, it governs the motion of planets, tides, and other natural phenomena.
| 4. How did Isaac Newton contribute to our understanding of gravitation? | |
Ans. Isaac Newton formulated the laws of motion and the law of universal gravitation, which revolutionized our understanding of gravitation. His laws mathematically described the force of gravity and explained the motion of objects on Earth and in space.
| 5. Can gravitation be shielded or canceled out? | |
Ans. Gravitation cannot be shielded or canceled out completely. However, certain forces, such as electromagnetic forces, can counteract the effects of gravity to some extent. For example, objects can experience apparent weightlessness in space due to the absence of normal forces opposing gravity.
