Physics (SSC IX-X) flashcards for Aga Khan University Examination Board

21 of 51 cards from the Physics (SSC IX-X) deck — real questions with worked answers.

1. What is a physical quantity?

   A quantity that can be measured and expressed in terms of a number (magnitude) and a unit, e.g. 5 metres.

2. What is the difference between base (fundamental) quantities and derived quantities? Give one example of each.

   Base quantities are independent and cannot be defined in terms of others (e.g. length, mass, time); derived quantities are obtained by combining base quantities (e.g. speed, force, area).

3. List the seven SI base quantities and their SI units.

   Length – metre (m); Mass – kilogram (kg); Time – second (s); Electric current – ampere (A); Temperature – kelvin (K); Amount of substance – mole (mol); Luminous intensity – candela (cd).

4. What is the SI unit of force and how is it derived from base units?

   The newton (N); 1 N = 1 kg·m·s⁻², derived from mass, length and time.

5. Define an international system unit (SI) and state why a standardised system is needed.

   SI (Système International) is the worldwide agreed system of units; it is needed so measurements are consistent and comparable everywhere, avoiding confusion between different unit systems.

6. What are the SI prefixes for 10⁻⁹, 10⁻⁶, 10⁻³, 10³, 10⁶, and 10⁹ along with their symbols?

   nano (n) = 10⁻⁹; micro (µ) = 10⁻⁶; milli (m) = 10⁻³; kilo (k) = 10³; mega (M) = 10⁶; giga (G) = 10⁹.

7. What is scientific (standard) notation and write 0.00045 in it.

   A way of writing numbers as a × 10ⁿ where 1 ≤ a < 10 and n is an integer; 0.00045 = 4.5 × 10⁻⁴.

8. Express 384,000,000 m in scientific notation.

   3.84 × 10⁸ m.

9. Convert 5 milliseconds (ms) into seconds.

   5 ms = 5 × 10⁻³ s = 0.005 s.

10. Which prefixes correspond to 10⁻¹², 10⁻², and 10¹², with their symbols?

    pico (p) = 10⁻¹²; centi (c) = 10⁻²; tera (T) = 10¹².

11. What is the least count of a measuring instrument?

    The smallest measurement that an instrument can read accurately; e.g. the least count of a metre rule is 1 mm (0.1 cm).

12. What is the least count of a Vernier callipers and what is it used to measure?

    0.1 mm (0.01 cm); used to measure small lengths such as the internal/external diameter and depth of objects.

13. What is the least count of a screw gauge (micrometer) and what is it used for?

    0.01 mm (0.001 cm); used to measure very small thicknesses such as the diameter of a wire or thickness of a sheet.

14. What is zero error in an instrument and what are its two types?

    Zero error occurs when an instrument does not read zero when it should; it is positive (zero of moving scale to the right of reference) or negative (to the left), and must be added or subtracted to correct readings.

15. How is the least count of a Vernier callipers calculated?

    Least count = value of one main scale division ÷ total number of Vernier scale divisions (e.g. 1 mm ÷ 10 = 0.1 mm).

16. How is the least count of a screw gauge calculated?

    Least count = pitch of the screw ÷ number of divisions on the circular (rotating) scale (e.g. 0.5 mm ÷ 50 = 0.01 mm).

17. What are significant figures?

    The accurately known digits in a measurement plus the first doubtful (estimated) digit; they reflect the precision of the measurement.

18. How many significant figures are in 0.00408 and in 5.300?

    0.00408 has 3 significant figures; 5.300 has 4 significant figures (trailing zeros after a decimal point are significant).

19. What is the difference between a random error and a systematic error?

    A random error varies unpredictably and can be reduced by taking repeated readings and averaging; a systematic error is a consistent error (e.g. zero error or faulty instrument) that biases results in one direction.

20. How can random errors be minimised in measurements?

    By taking several repeated readings and calculating their average (mean), which reduces the effect of unpredictable variations.

21. Define rest and motion.

    A body is at rest if it does not change its position with respect to its surroundings over time; it is in motion if it changes its position with respect to its surroundings over time.
