1. Which instrument is used to measure mass?
A. Vernier caliper
B. Beam balance
C. Ammeter
D. Thermometer
Answer: B. Beam balance
Explanation: Mass is measured using a beam balance or electronic balance. A thermometer
measures temperature, and an ammeter measures electric current.
2. What is the SI unit of force?
A. Joule
B. Newton
C. Pascal
D. Watt
Answer: B. Newton
Explanation: Force is measured in newtons (N), where 1 N = 1 kg·m/s².
3. What physical quantity is measured in joules?
A. Power
B. Work or Energy
C. Pressure

D. Velocity
Answer: B. Work or Energy
Explanation: Work and energy are measured in joules (J). 1 joule = work done when 1 newton
moves an object 1 meter.
4. A car travels 100 km in 2 hours. Its average speed is:
A. 25 km/h
B. 50 km/h
C. 75 km/h
D. 100 km/h
Answer: B. 50 km/h
Explanation: Speed = Distance ÷ Time = 100 ÷ 2 = 50 km/h.
5. What is the acceleration of an object whose velocity changes from 0 to 20 m/s in 5 s?
A. 2 m/s²
B. 4 m/s²
C. 5 m/s²
D. 10 m/s²
Answer: B. 4 m/s²

Explanation: a=v−ut=20−05=4 m/s2a = \frac{v - u}{t} = \frac{20 - 0}{5} = 4 \, m/s^2a=tv−u
=520−0=4m/s2
6. Which law states that “every action has an equal and opposite reaction”?
A. Newton’s First Law
B. Newton’s Second Law
C. Newton’s Third Law
D. Hooke’s Law
Answer: C. Newton’s Third Law
Explanation: The law means that forces always come in pairs — when object A exerts a force
on B, B exerts an equal and opposite force on A.
7. What type of energy does a moving car possess?
A. Potential energy
B. Kinetic energy
C. Thermal energy
D. Elastic energy
Answer: B. Kinetic energy
Explanation: Any object in motion has kinetic energy, given by KE=12mv2KE = \frac{1}
{2}mv^2KE=21mv2.

8. What is the density of a material with mass 200 g and volume 50 cm³?
A. 2 g/cm³
B. 3 g/cm³
C. 4 g/cm³
D. 5 g/cm³
Answer: C. 4 g/cm³
Explanation: Density = Mass ÷ Volume = 200 ÷ 50 = 4 g/cm³.
9. Which of the following is not a vector quantity?
A. Force
B. Velocity
C. Mass
D. Acceleration
Answer: C. Mass
Explanation: Vector quantities have both magnitude and direction; mass has only magnitude, so
it’s a scalar.
10. The slope of a distance-time graph represents:
