Physics Chapter 1 (Topic3 : Base and Derived Quantities)
Differentiate between base and derived physical quantities and units. Question(s) will be asked in final examination.
1 / 30
What is a base physical quantity?
Reasoning: Base quantities are fundamental and independent (e.g., length, mass, time).
2 / 30
Which of the following is a base physical quantity?
Reasoning: Mass is one of the seven SI base quantities.
3 / 30
What is a derived physical quantity?
Reasoning: Derived quantities are obtained from base quantities (e.g., speed, force).
4 / 30
Which of the following is a derived quantity?
Reasoning: Velocity is derived from length and time.
5 / 30
Which pair contains only base quantities?
Reasoning: Mass and time are both base quantities.
6 / 30
Which of the following is NOT a base quantity?
Reasoning: Force is derived, not fundamental.
7 / 30
Which of the following correctly represents a derived unit?
Reasoning: Newton is derived (kg m/s²).
8 / 30
What is the SI unit of a base quantity always called?
Reasoning: Base quantities have fundamental SI units.
9 / 30
Which of the following is NOT a derived quantity?
Reasoning: Mass is a base quantity.
10 / 30
Which combination correctly forms speed?
Reasoning: Speed = Distance / Time
11 / 30
Which statement about base quantities is correct?
Reasoning: Base quantities are independent and fundamental.
12 / 30
Which of the following is a derived unit?
Reasoning: Newton is derived from base units.
13 / 30
What is the unit of a derived quantity formed from base units?
Reasoning: Derived units are combinations of base units.
14 / 30
Which is NOT a correct base quantity and unit pair?
Reasoning: Force is derived, not base.
15 / 30
Which of the following is an example of a derived quantity?
Reasoning: Area is derived from length × length.
16 / 30
What is the relationship between base and derived quantities?
Reasoning: Derived quantities come from base quantities.
17 / 30
Which of the following is a base unit?
Reasoning: Meter is a base unit of length.
18 / 30
Which of the following is a derived unit of pressure?
Reasoning: Pressure = force / area = N/m²
19 / 30
Why is force considered a derived quantity?
Reasoning: Force = mass × acceleration
20 / 30
Which of the following is NOT formed from base quantities?
Reasoning: Time is a base quantity.
21 / 30
Which of the following correctly distinguishes base from derived quantities?
Reasoning: Derived quantities are formed using base quantities.
22 / 30
Which is an example of a derived quantity involving two base quantities?
Reasoning: Speed = length / time
23 / 30
Which of the following is NOT a characteristic of base quantities?
Reasoning: Base quantities are not derived.
24 / 30
Which physical quantity is derived from force and distance?
Reasoning: Work = force × distance
25 / 30
Which statement is correct about SI system?
Reasoning: SI system is built on base quantities.
26 / 30
Which of the following is a correct derived unit?
Reasoning: kg m/s² is Newton (force).
27 / 30
Why is area considered a derived quantity?
Reasoning: Area = length × length
28 / 30
Which of the following is a correct base quantity set?
Reasoning: These are fundamental SI base quantities.
29 / 30
What is the key difference between base and derived quantities?
Reasoning: Dependency is the key difference.
30 / 30
Which of the following correctly describes derived quantities?
Reasoning: Derived quantities come from mathematical combinations of base quantities.
