Frequently Asked Questions
How to prepare for NEET Physics?
For NEET Physics preparation, focus on NCERT textbooks first, then move to reference books. Create a topic-wise study plan covering Mechanics, Thermodynamics, Electromagnetism, Optics, and Modern Physics. Solve previous years’ questions and take regular mock tests. Pay special attention to conceptual clarity and numerical problem-solving skills.
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.
