Questions and Answers on NDA General Knowledge Physics
This blog is all about questions and answers on NDA General Knowledge Physics. If you’re looking for a resource to ask questions or get answers on this subject, you’ve come to the right place.
Q: What is energy?
A: Energy is the capacity to do work. It can be stored in physical or chemical forms, and it can be transferred between objects or substances.
Q: How does energy create motion?
A: Energy can be converted into motion by either creating heat or moving objects. When heat is applied to an object, its molecules move faster than they would if no heat was applied. This increased speed creates motion, which is why things like boiling water produce sound because the molecules are moving faster than the sound waves can travel. Similarly, when objects are moved, their kinetic energy (energy associated with movement) is converted into other forms of energy (like thermal energy).
Q: What is the difference between a normal law and natural law?
A: A normal law is a statute or rule that has been created by humans, while natural law is an unchanging principle that governs the universe.
Q: What is an electron?
A: An electron is a small, negatively charged particle that orbits the nucleus of an atom. It has a mass about half that of the proton and occupies just one-seventh of the nuclei’s space.
Q: What is the difference between a normal law and natural law?
A: A normal law is a statute or rule that has been created by humans, while natural law is an unchanging principle that governs the universe.
