Introduction
This examination assesses foundational and applied knowledge in physics, covering
mechanics, energy, waves, electricity, magnetism, and optics. It evaluates conceptual
understanding, quantitative reasoning, and the ability to apply physical principles to
real-world scenarios. Multiple-choice and scenario-based questions test critical
thinking, decision-making, and professional judgment. The exam emphasizes
practical application, regulatory awareness, and ethical standards relevant to physics
practice. Candidates must demonstrate mastery of core theories, experimental
,methods, and problem-solving skills essential for advanced study and professional
work in physical sciences.
SECTION ONE: QUESTIONS 1–50
Question 1
A car travels 150 meters north in 10 seconds, then 150 meters south in 15 seconds.
What is the average speed and average velocity for the entire trip?
A. Average speed = 12 m/s; average velocity = 0 m/s
B. Average speed = 12 m/s; average velocity = 6 m/s north
C. Average speed = 0 m/s; average velocity = 12 m/s
D. Average speed = 15 m/s; average velocity = 0 m/s
🟢 Correct Answer: A. Average speed = 12 m/s; average velocity = 0 m/s
🔴 Explanation: Average speed = total distance / total time = (150 + 150) / (10 +
15) = = 12 m/s. Average velocity = displacement / total time = = 0
m/s because the car returns to its starting point.
Question 2
Which of the following is a vector quantity?
A. Mass
B. Temperature
C. Displacement
D. Time
🟢 Correct Answer: C. Displacement
🔴 Explanation: Displacement has both magnitude and direction, making it a
vector. Mass, temperature, and time are scalar quantities with magnitude only.
,Question 3
A projectile is launched at 30 degrees above the horizontal with an initial speed of
40 m/s. What is the horizontal component of its initial velocity?
A. 20 m/s
B. 34.6 m/s
C. 40 m/s
D. 17.3 m/s
🟢 Correct Answer: B. 34.6 m/s
🔴 Explanation: Horizontal component = v₀ cos θ = 40 cos 30° = 40 × 0.866 = 34.6
m/s.
Question 4
Newton's First Law of Motion states that an object at rest remains at rest unless
acted upon by:
A. A balanced force
B. An unbalanced force
C. Gravity alone
D. Friction alone
🟢 Correct Answer: B. An unbalanced force
🔴 Explanation: Newton's First Law (law of inertia) states that an object remains at
rest or in uniform motion unless acted upon by a net external (unbalanced) force.
Question 5
A 5 kg block is pushed with a force of 20 N on a frictionless surface. What is its
acceleration?
, A. 2 m/s²
B. 4 m/s²
C. 5 m/s²
D. 100 m/s²
🟢 Correct Answer: B. 4 m/s²
🔴 Explanation: According to Newton's Second Law, F = ma, so a = F/m = 20 N / 5
kg = 4 m/s².
Question 6
What is the SI unit of work?
A. Newton
B. Watt
C. Joule
D. Pascal
🟢 Correct Answer: C. Joule
🔴 Explanation: Work is defined as force times displacement. The SI unit is the
joule (J), where 1 J = 1 N·m.
Question 7
A 2 kg object is lifted 5 meters vertically. What is the gravitational potential energy
gained? (g = 9.8 m/s²)
A. 49 J
B. 98 J
C. 10 J
D. 20 J
🟢 Correct Answer: B. 98 J
