Physics Theory Questions and Answers

Physics theory questions in WAEC require detailed explanations and calculations. Below are some frequently asked questions along with model answers:

Question 1: Define Work, Energy, and Power

Answer:

Work is defined as the product of force and displacement in the direction of force.

Energy is the ability to do work. It exists in various forms, such as kinetic energy and potential energy.

Power is the rate at which work is done, expressed as power = work/time.

Question 2: State Newton’s Laws of Motion

Answer:

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

Second Law: The acceleration of an object is directly proportional to the force applied and inversely proportional to its mass (F = ma).

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

Question 3: Explain the Principle of Conservation of Energy

Answer:
The principle states that energy cannot be created or destroyed but can only be transformed from one form to another.

The total energy of an isolated system remains constant.
