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 years’ 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.

How do you solve projectile motion problems?

To solve projectile motion problems, break the motion into horizontal and vertical components. The horizontal motion has constant velocity (ax = 0), while the vertical motion has constant acceleration due to gravity (ay = g). Use the equations of motion separately for each component, and remember that the time is the same for both components.

What is the difference between electric potential and electric potential energy?

Electric potential is the electric potential energy per unit charge, measured in volts (V). It’s a property of a point in space. Electric potential energy is the energy possessed by a charge due to its position in an electric field, measured in joules (J). It depends on both the charge and its position.
