Frequently Asked Questions (Chapter-Wise)

Laws of Motion: State Newton’s laws with examples, derive centripetal force.
Work, Power & Energy: Derive work-energy theorem, define potential and kinetic energy.
Gravitation: Derive expression for acceleration due to gravity, explain satellites in orbit.
Oscillations: Derive equation of SHM, explain pendulum motion.
Waves: Explain principle of superposition, derive speed of wave in a string.
Thermodynamics: State and explain first and second law, explain heat engines.

Numerical Questions

Problems on motion under gravity.
Numericals on work, energy, and power.
Calculation of escape velocity and orbital velocity.
Oscillation time period calculations.

Why These Questions Are Important

These questions are important because they are repeated in exams almost every year. Practicing them not only ensures passing marks but also helps in building strong concepts for Class 12 and competitive exams like JEE/NEET.
