Frequently Asked Questions
How to prepare for IIT-JEE Physics?
To prepare for IIT-JEE Physics, focus on understanding concepts rather than memorizing formulas. Practice solving a variety of problems, especially previous yearsβ questions. Create a study schedule that covers all topics, with extra time for challenging areas like Mechanics and Electromagnetism. Regular revision and mock tests are essential for success.
What is the difference between elastic and inelastic collisions?
In elastic collisions, both momentum and kinetic energy are conserved. Examples include collisions between hard billiard balls. In inelastic collisions, only momentum is conserved while some kinetic energy is converted to other forms like heat or sound. Most real-world collisions are inelastic to some degree.
How does electromagnetic induction work?
Electromagnetic induction is the process of generating an electromotive force (EMF) in a conductor by changing the magnetic field through it. According to Faradays Law, the induced EMF is proportional to the rate of change of magnetic flux. This principle is the basis for generators, transformers, and inductors, which are essential components in electrical power systems.
