WAEC GCE Engineering Science 2025 Essay Questions and Answers

Question 1:

Explain three forms of energy and their applications in engineering.

Answer:

1. Kinetic Energy: The energy of moving objects used in turbines and engines.

2. Potential Energy: Stored energy in elevated bodies, applied in cranes and lifts.

3. Electrical Energy: Generated from power plants to operate machines, motors, and lighting systems.

Question 2:

State and explain three laws of motion.

Answer:

1. First Law (Law of Inertia): An object remains at rest or in uniform motion unless acted upon by an external force.

2. Second Law: Force equals mass multiplied by acceleration (F = ma).

3. Third Law: For every action, there is an equal and opposite reaction.

Question 3:

Define work, energy, and power.

Answer:

• Work: The product of force and distance moved in the direction of the force.
  Formula: W = F × d

• Energy: The ability to do work.

• Power: The rate of doing work.
  Formula: P = W/t

Question 4:

Explain three methods of heat transfer and give one example of each.

Answer:

1. Conduction: Transfer through solids (e.g., a metal rod heating up).

2. Convection: Transfer through fluids (e.g., boiling water).
