Physics (HSSC) flashcards for FBISE Examinations
24 of 51 cards from the Physics (HSSC) deck — real questions with worked answers.
What is a physical quantity, and into what two categories are physical quantities divided?
A physical quantity is one that can be measured and expressed as a number with a unit. They are divided into base (fundamental) quantities and derived quantities.
Name the seven SI base quantities and their SI base units.
Length (metre, m), Mass (kilogram, kg), Time (second, s), Electric current (ampere, A), Temperature (kelvin, K), Amount of substance (mole, mol), and Luminous intensity (candela, cd).
What are the three supplementary SI units?
Radian (rad) for plane angle and steradian (sr) for solid angle. (Note: older HSSC texts list these two as supplementary units.)
Define a derived unit and give three examples.
A derived unit is formed by combining base units through multiplication or division. Examples: newton (kg·m·s^-2), joule (kg·m^2·s^-2), watt (kg·m^2·s^-3).
What is the difference between precision and accuracy in measurement?
Accuracy is how close a measured value is to the true value (related to absolute uncertainty). Precision is how close repeated measurements are to each other (related to the least count of the instrument / fractional uncertainty).
Define significant figures.
Significant figures are the accurately known digits in a measurement plus the first doubtful (estimated) digit. They indicate the precision of a measurement.
State the rule for significant figures when adding or subtracting quantities.
The result is rounded to the same number of decimal places as the quantity with the fewest decimal places.
State the rule for significant figures when multiplying or dividing quantities.
The result must have the same number of significant figures as the quantity with the fewest significant figures.
What are systematic errors and how can they be reduced?
Systematic errors occur due to faulty instruments, zero error, or incorrect calibration; they affect results consistently in one direction. They can be reduced by correcting/calibrating instruments and applying corrections.
What are random errors and how can they be reduced?
Random errors arise from unpredictable fluctuations and vary in size and sign. They are reduced by taking many readings and computing the mean (average) value.
How is the absolute uncertainty in a single reading taken as?
It is taken as the least count of the measuring instrument (the smallest division it can read).
How do uncertainties combine when two quantities are added or subtracted?
The absolute uncertainties are added: if Q = A ± B, then ΔQ = ΔA + ΔB.
How do uncertainties combine when two quantities are multiplied or divided?
The percentage (fractional) uncertainties are added: total %uncertainty = %uncertainty in A + %uncertainty in B.
How does uncertainty propagate when a quantity is raised to a power n?
The percentage uncertainty is multiplied by the power: if Q = A^n, then %uncertainty in Q = n × (%uncertainty in A).
What is the dimension of a physical quantity?
The dimension expresses a quantity in terms of the base quantities using symbols, typically [L] for length, [M] for mass, and [T] for time (and [I], [Θ], etc.).
What are the dimensions of force, work/energy, and power?
Force: [M L T^-2]; Work/Energy: [M L^2 T^-2]; Power: [M L^2 T^-3].
State the two main uses of dimensional analysis.
(1) To check the correctness (homogeneity) of a physical equation, and (2) to derive a possible relationship/formula between physical quantities.
State the principle of homogeneity of dimensions.
A physical equation is dimensionally correct only if the dimensions of every term on both sides of the equation are the same.
Give two limitations of dimensional analysis.
It cannot determine dimensionless constants (like 1/2 or 2π) and cannot derive equations involving trigonometric, exponential, or logarithmic functions, or equations with more than three unknowns.
What is the difference between a scalar and a vector quantity?
A scalar has only magnitude (e.g., mass, time, speed). A vector has both magnitude and direction (e.g., displacement, force, velocity) and obeys vector addition rules.
State the head-to-tail rule for vector addition.
Place vectors so the tail of each successive vector touches the head of the previous one; the resultant is drawn from the tail of the first vector to the head of the last vector.
How are the rectangular components Ax and Ay of a vector A making angle θ with the x-axis found?
Ax = A cos θ and Ay = A sin θ.
Given components Ax and Ay, how do you find the magnitude and direction of the vector?
Magnitude A = √(Ax² + Ay²); Direction θ = tan^-1(Ay / Ax) measured from the x-axis.
What is a unit vector and how is it obtained from a vector A?
A unit vector has magnitude 1 and indicates direction only. It is obtained by = A / |A|.
Planning Physics (HSSC) for FBISE Examinations
Physics (HSSC) is about 24% of the FBISE Examinations syllabus by topic count — 32 of 136 topics, spread over 10 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 25 hours.
The heaviest chapters are Vectors and Equilibrium (4 topics), Electrostatics (4 topics), Measurements (3 topics) . Front-load those while your energy is high; the short chapters are better revision filler later.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
