Class 11 Physics - Detailed Notes
CLASS 11 PHYSICS - DETAILED NOTES
CHAPTER 1: PHYSICAL WORLD
- **Physics**: Study of nature and its laws.
- **Branches of Physics**:
- Classical Physics: Mechanics, Thermodynamics, Electromagnetism.
- Modern Physics: Quantum Mechanics, Relativity.
- **Scientific Method**: Observation -> Hypothesis -> Experiment -> Theory.
CHAPTER 2: UNITS AND MEASUREMENTS
- **Fundamental Quantities**: Length, Mass, Time, etc.
- **SI Units**: Meter (m), Kilogram (kg), Second (s), etc.
- **Dimensional Analysis**: Checking correctness of equations.
- **Significant Figures**: Precision in measurements.
CHAPTER 3: MOTION IN A STRAIGHT LINE
- **Kinematics**: Study of motion without considering forces.
- **Equations of Motion**:
- v = u + at
- s = ut + 1/2 at²
- v² = u² + 2as
- **Graphical Analysis**: Velocity-time, Acceleration-time graphs.
CHAPTER 4: MOTION IN A PLANE
- **Vectors and Scalars**: Magnitude & Direction.
- **Projectile Motion**:
- Horizontal Range: R = (u² sin 2theta)/g
- Time of Flight: T = (2u sintheta)/g
- **Relative Velocity**: Velocity of one object w.r.t another.
