Why Physics Matters
Physics in MDCAT: The Conceptual Challenge
Physics contributes 40 out of 200 marks in the MDCAT exam, accounting for 20% of the total score. While it carries fewer marks than Biology and Chemistry, Physics is often considered the most challenging subject by MDCAT aspirants due to its emphasis on conceptual understanding and mathematical problem-solving. The PMC MDCAT Physics syllabus covers the entire FSc Pre-Medical Physics curriculum, including classical mechanics, thermodynamics, waves and optics, electricity and magnetism, and modern physics topics that form the foundation of medical imaging, radiation therapy, and biomedical engineering.
The Physics section of MDCAT tests your ability to apply fundamental principles to solve problems, interpret graphs, analyze physical phenomena, and perform calculations under time pressure. Questions range from straightforward unit conversions and formula applications to multi-step numerical problems that require combining concepts from different chapters. Optics, Current Electricity, and Motion and Force are historically the highest-yield chapters, but no chapter should be neglected as questions can come from any topic. Our collection of 12,000+ Physics MCQs provides comprehensive chapter-wise coverage of the entire PMC MDCAT 2026 Physics syllabus. Each question is designed to build your conceptual clarity and numerical problem-solving speed. From basic definitions to complex application-based problems, our question bank ensures you are prepared for every type of question you might encounter on exam day. With detailed step-by-step solutions for every MCQ, PrepMDCAT helps you understand the physics behind each answer, turning your weakest subject into a scoring opportunity.

Solved MCQs with Explanations
MDCAT Physics MCQs with Detailed Answers
Understanding the "why" behind each answer is crucial for MDCAT success. Here are sample MCQs with comprehensive explanations to help you build deep conceptual understanding.
Q1. The dimension of force is:
- A) [MLT⁻¹]
- B) [MLT⁻²]
- C) [ML²T⁻²]
- D) [ML⁻¹T⁻²]
Correct Answer: B) [MLT⁻²]
Force = mass × acceleration = [M][LT⁻²] = [MLT⁻²]. Dimensional analysis is a fundamental skill in Physics that helps verify equations, derive relationships between physical quantities, and convert between unit systems.
Q2. The range of a projectile is maximum when angle of projection is:
- A) 30°
- B) 45°
- C) 60°
- D) 90°
Correct Answer: B) 45°
Range R = v²sin2θ/g is maximum when sin2θ = 1, i.e., 2θ = 90°, so θ = 45°. Note that complementary angles (e.g., 30° and 60°) give the same range. At 45°, the horizontal and vertical components of initial velocity are equal, providing the optimal balance for maximum distance.
Q3. The escape velocity from Earth's surface is approximately:
- A) 7.9 km/s
- B) 11.2 km/s
- C) 3.0 × 10⁸ m/s
- D) 340 m/s
Correct Answer: B) 11.2 km/s
Escape velocity vₑ = √(2gR) ≈ 11.2 km/s is the minimum velocity needed for an object to escape Earth's gravitational field without further propulsion. The orbital velocity for a satellite near Earth's surface is approximately 7.9 km/s. Note that 3×10⁸ m/s is the speed of light, and 340 m/s is the speed of sound in air.
Q4. 1 horsepower equals:
- A) 550 W
- B) 746 W
- C) 1000 W
- D) 100 W
Correct Answer: B) 746 W
1 horsepower (hp) = 746 watts. Power is the rate of doing work, P = W/t = Fv. This is an important unit conversion that frequently appears in MDCAT Physics. Remember: 1 hp = 746 W, 1 kW = 1000 W.
Q5. In Atwood machine with m₁ > m₂, acceleration is:
- A) a = (m₁+m₂)g/(m₁-m₂)
- B) a = (m₁-m₂)g/(m₁+m₂)
- C) a = m₁g/m₂
- D) a = g
Correct Answer: B) a = (m₁-m₂)g/(m₁+m₂)
In an Atwood machine (two masses connected by a string over a pulley), the acceleration a = (m₁-m₂)g/(m₁+m₂) and the tension T = 2m₁m₂g/(m₁+m₂). The acceleration is always less than g because the system's total mass (m₁+m₂) resists the net force (m₁-m₂)g.
