Important Points to Remember – Class 11 Physics

• The SI system (Système Internationale d’ Unites) is the internationally accepted system of measurement, revised by the General Conference on Weights and Measures in November 2018
• Fundamental quantities have base units (length-meter, mass-kilogram, time-second) while derived quantities have derived units formed by combinations of base units
• Motion is defined as change in position of an object with time, and kinematics studies motion without considering its causes
• Instantaneous velocity is the limiting value of average velocity as time interval approaches zero, representing velocity at a specific instant
• Uniform acceleration occurs when an object’s velocity changes by equal amounts in equal time intervals along a straight line
• Scalars have only magnitude (distance, mass, temperature) while vectors have both magnitude and direction (displacement, velocity, acceleration)
• Projectile motion is a combination of uniform horizontal motion and uniformly accelerated vertical motion under gravity
• Newton’s First Law states that an object at rest stays at rest and an object in motion stays in uniform motion unless acted upon by external force
• Newton’s Second Law establishes that Force = mass × acceleration (F = ma), connecting force with motion quantitatively
• Newton’s Third Law states that for every action there is an equal and opposite reaction, forces always occur in pairs
• Significant figures represent the precision of a measurement and follow specific rules for mathematical operations
• Dimensional analysis uses the fundamental dimensions [M], [L], [T] to check equation validity and derive relationships
• Relative velocity depends on the reference frame chosen and is calculated by vector subtraction of velocities
• Uniform circular motion involves constant speed but changing velocity due to continuous change in direction
• The kinematic equations apply only to uniformly accelerated motion in a straight line and form the foundation for solving motion problems

Quick Revision Notes – Class 11 Physics

• Remember the evolution: CGS (cm-g-s) → FPS (ft-lb-s) → MKS (m-kg-s) → SI system for better historical understanding in exams
• For significant figures: multiplication/division follows least significant figures rule, addition/subtraction follows least decimal places rule
• Velocity-time graphs: slope gives acceleration, area under curve gives displacement – crucial for graphical problem solving
• Vector addition follows triangle law and parallelogram law; subtraction is addition of negative vector – draw clear diagrams
• In projectile motion, horizontal component of velocity remains constant while vertical component changes due to gravity
• Time of flight, maximum height, and range formulas in projectile motion are frequently asked in board exams with numerical values
• Newton’s laws form interconnected concepts: First law defines inertia, Second law quantifies force, Third law explains force pairs
• Free body diagrams are essential for solving force problems – identify all forces acting on the object clearly
• Circular motion concepts: centripetal acceleration always points toward center, centripetal force is provided by other forces
• Distinguish between distance-displacement, speed-velocity, and acceleration types for conceptual clarity in objective questions
• Dimensional formula method helps verify derived equations and can be used to derive relationships between physical quantities
• Relative motion problems require careful selection of reference frame and proper vector operations for correct solutions
• Practice unit conversion problems extensively as they appear frequently in both objective and subjective sections
• Memorize standard values: g = 9.8 m/s², acceleration due to gravity varies slightly with location and altitude
• Focus on derivations of kinematic equations from basic definitions as step-by-step derivations carry significant marks in board exams
