While Paper 1 might cover basic concepts like Newton's laws and kinematics, Paper 2 typically delves deeper into:

Circular Motion: This involves understanding centripetal force, angular velocity, angular acceleration, and the application of Newton's laws in rotational contexts. Expect problems involving vertical circular motion, conical pendulums, and banked tracks.
Simple Harmonic Motion (SHM): This section requires a thorough grasp of the equations governing SHM, including displacement, velocity, acceleration, and energy considerations. You might encounter questions on mass-spring systems, simple pendulums, and damped oscillations.
Gravitation: This goes beyond simple calculations of gravitational force. Paper 2 often includes problems involving Kepler's laws, orbital velocities, escape velocity, and gravitational fields.
Work, Energy, and Power: This involves advanced applications of the work-energy theorem, conservation of energy, and power calculations in various scenarios, including those involving friction and variable forces.
Rotational Dynamics: This topic extends the concepts of mechanics to rotating bodies, involving torque, moment of inertia, angular momentum, and rotational kinetic energy. Expect problems involving rotating wheels, gyroscopes, and conservation of angular momentum.

B. Electricity and Magnetism: Deeper Exploration

Paper 2 typically expands on the introductory concepts of electricity and magnetism presented in Paper 1, focusing on:

Electric Fields and Potentials: This involves a deeper understanding of electric field lines, equipotential surfaces, Gauss's law, and the calculation of electric potential due to various charge distributions.
Capacitance and Dielectrics: This section explores the behavior of capacitors in circuits, the energy stored in capacitors, and the effect of dielectric materials on capacitance.
Direct Current (DC) Circuits: This goes beyond basic circuit analysis, involving more complex circuits with multiple resistors, capacitors, and sources of emf. Kirchhoff's laws are crucial for solving these problems.
Magnetic Fields and Forces: This involves the calculation of magnetic fields due to various current distributions (wires, loops, solenoids), the force on a moving charge in a magnetic field, and the force on a current-carrying conductor in a magnetic field.
Electromagnetic Induction: This is a key area covering Faraday's law, Lenz's law, and the operation of generators and transformers. Problems may involve calculating induced emf and current in various situations.
Alternating Current (AC) Circuits: Understanding AC circuits requires familiarity with root mean square (RMS) values, impedance, phase relationships, and resonance in RLC circuits.
