WAEC 2025 Physics Likely Theory Questions and Answers

Here are some possible theory questions, based on previous WAEC patterns and syllabus topics.

Question 1

State Newton’s First Law of Motion.

✅ Answer:
Newton’s First Law of Motion states that a body will remain at rest or move in a straight line with constant speed unless acted upon by a force.

Question 2

A body of mass 5 kg is accelerated by a force of 20 N. Calculate its acceleration.

✅ Answer:
Using $F = ma$ ,
$\frac{F}{m} = \frac{20}{5} = 4 \, \text{m/s}^2$

Question 3

Define specific heat capacity and give its SI unit.

✅ Answer:
Specific heat capacity is the quantity of heat required to raise the temperature of 1 kg of a substance by 1°C (or 1K).
SI Unit: $J/kg\cdotpK\text{J/kg·K}$

Question 4

List two factors that affect the resistance of a wire.

✅ Answer:

Length of the wire
Cross-sectional area
Material of the wire
Temperature

Question 5

State two differences between a convex and a concave lens.

✅ Answer:

Convex Lens	Concave Lens
Converges light rays	Diverges light rays
Can form real images	Forms only virtual images
