Physics WAEC Past Questions.

Published on Jul 29, 2025 • Education

Introduction

Good day, students!
My name is Siri, and welcome to today’s physics class. Get your writing materials and calculators ready, because we’ll be tackling important physics past questions that are likely to appear in exams like WAEC, NECO, and JAMB.

This session focuses on derived units, motion graphs, and pressure concepts — foundational topics you must understand for excellent performance.

Let’s get started with the questions and answers.

Question 1: Derived Units

Question:
Which of the following physical quantities are derived?

• Area
• Thrust
• Pressure
• Mass

Explanation

• Area is derived from length × breadth (m²).
• Thrust (force) is derived from mass × acceleration (N).
• Pressure is derived from force ÷ area (N/m²).
• Mass is a fundamental quantity, not derived.

Therefore, the correct answer is the group excluding mass.

Question 2: Slope of a Displacement-Time Graph

Question:
The slope of a straight-line displacement-time graph indicates ______.
