MASTERING PHYSICS QUESTIONS AND ANSWERS What is Newton's law of gravitation? - ANSWER Every body in the universe attracts every other body with a mutually attracting force. For two bodies, this force is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them. What is the expression for a gravitational force? Assume that m1 and m2 are the masses, d is the distance between their centers, G is the universal constan...

sociological imagination - ANSWERSa term coined by C. Wright Mills. The ability to see the connections between our personal experience and the larger forces of history. "The first fruit of this imagination—and the first lesson of the social science that embodies it—is the idea that the individual can understand his own experience and gauge his own fate only by locating himself within his period, that he can know his own chances in life only by becoming aware of those of all individuals in h...

Certainly! Let's delve into the first chapter of Class 11 Physics, which is **"Physical World."** This chapter provides an overview of the broad and diverse field of physics. Here are some key points: 1. **Scope of Physics**: Physics explores the fundamental forces that govern nature, the inherent nature of physical laws, and their impact on our world. It encompasses the study of matter, energy, and their interactions. 2. **Interaction with Technology and Society**: Physics plays a cruc...

CBSE Class 12 Physics Chapter 1 covers Electric Charges and Fields. These revision notes serve as a concise recap of key concepts. It begins with the fundamental properties of electric charge, introducing concepts like conservation and quantization of charge. Coulomb's law, governing the force between charges, is explained, along with the principle of superposition. Electric field and its representation are crucial topics, followed by lines of force and its properties. Gauss's law, a powerful ...
