## Class 12 Physics Important Numericals for HSC Board Exam **Important Topics and Related Numericals:** 1. **Kinematics:** * Describe an object's motion using equations to find its final velocity or displacement. 2. **Laws of Motion:** * Use Newton's laws to calculate the forces and acceleration acting on a body. 3. **Work, Energy, and Power:** * Apply the work done formula to calculate the work, kinetic energy, or potential energy of an object. For example, calculate the work done in lifting an object to a certain height. 4. **Gravitation:** * Calculate the gravitational force between two masses given their masses and separation distance. For example, calculate the gravitational force between two masses of 5 kg and 10 kg, separated by 2 m, given G = 6.67 x 10^-11 N m²/kg². 5. **Thermodynamics:** * Calculate the final pressure of a gas when its volume changes, assuming an ideal gas. For example, given an initial volume of 2 m³, an initial pressure of 1.5 x 10^5 Pa, and a final volume of 4 m³, calculate the final pressure. 6. **Oscillations:** * Calculate the stretch of a spring when a mass is attached to it, given the spring constant. For example, given a spring constant of 200 N/m and a mass of 2 kg, calculate the stretch of the spring. 7. **System of Particles and Rotational Motion:** * Use formulas to calculate the moment of inertia of a rotating body. Determine the torque and angular momentum acting on the body. 8. **Mechanical Properties of Solids and Fluids:** * Calculate stress, strain, and Young's modulus in solids. Solve problems in fluid mechanics using Bernoulli's equation. 9. **Thermodynamics:** * Use the first law of thermodynamics to calculate heat transfer and work done. 10. **Oscillations and Waves:** * Use equations of simple harmonic motion to calculate displacement, velocity, and acceleration. Relate wave speed, frequency, and wavelength. 11. **Optics:** * Apply lens and mirror formulas to calculate image distance and magnification. 12. **Electrostatics and Current Electricity:** * Calculate the force between charges using Coulomb's law. Apply Ohm's law to determine current, voltage, and resistance. **Practice these topics thoroughly as they are important for the exam.** If you need help with any specific numerical problem, feel free to ask.
