1. What is the SI unit of force?
A. Joule
B. Newton
C. Pascal
D. Watt
Rationale: Force is measured in newtons under the SI unit system.
2. Which law states that pressure is inversely proportional to volume at
constant temperature?
A. Charles’s Law
B. Gay-Lussac’s Law
C. Avogadro’s Law
D. Boyle’s Law
Rationale: Boyle’s Law describes the inverse pressure–volume
relationship.
3. The area under a velocity–time graph represents:
A. Acceleration
B. Jerk
C. Displacement
D. Force
Rationale: The area under the velocity–time curve equals displacement.
,4. A right triangle with sides 3 and 4 has a hypotenuse of:
A. 5
B. 6
C. 5
D. 7
Rationale: By the Pythagorean theorem, √(3² + 4²) = 5.
5. Ohm’s Law relates voltage, current, and:
A. Power
B. Resistance
C. Resistance
D. Capacitance
Rationale: Ohm’s Law is V = IR, which connects voltage, current, and
resistance.
6. The slope of a stress–strain curve in the elastic region is called:
A. Yield strength
B. Ultimate strength
C. Modulus of Elasticity
D. Toughness
Rationale: The elastic slope defines Young’s modulus.
7. Which material property describes resistance to deformation?
A. Ductility
B. Stiffness
C. Malleability
D. Brittleness
Rationale: Stiffness is resistance to elastic deformation.
8. The derivative of displacement with respect to time is:
A. Jerk
B. Velocity
C. Acceleration
D. Momentum
Rationale: Velocity is the time derivative of displacement.
, 9. The integral of acceleration with respect to time gives:
A. Displacement
B. Velocity
C. Force
D. Power
Rationale: Integrating acceleration over time gives velocity.
10.In statistics, the median is:
A. The arithmetic average
B. The most frequent value
C. The middle value
D. The range
Rationale: The median is the middle value in an ordered data set.
11.The SI unit of power is:
A. Newton
B. Joule
C. Watt
D. Pascal
Rationale: Power is measured in watts.
12.Work is defined as:
A. Force divided by distance
B. Force times distance
C. Mass times acceleration
D. Power times time
Rationale: Work equals force multiplied by displacement.
13.Which of the following is a scalar quantity?
A. Velocity
B. Acceleration
C. Force
D. Temperature
Rationale: Temperature has magnitude only, no direction.
