Keep in mind that each process will receive a grade. So, when reporting and presenting your practical outcomes, make sure you don’t neglect any steps. Also, keep in mind that the units are quite crucial.

The Physics Practical question paper will consist of three areas and general Physics questions namely:

  1. Optics
  2. Electricity
  3. Mechanics

You will be expected to carry out an experiment, take readings and tabulate your values, plot graph, state precautions taken during the experiment, and report observation.

(xi) PRECAUTIONS
(i) I ensured that the meter rule balances horizontally before readings are taken in order to avoid experimental error.
(ii) I ensured that parallax error was avoided when taking the readings on The meter rule by viewing its calibration vertically.
(1bi) Moment of a force can be defined as the product of the force and its perpendicular distance from its point of action.
Moment of a force = force * Perpendicular distance of its line of action from the point
Moment = F * L
The S.I unit is Newton-meter(Nm).
It is a vector quantity(1bii)


x=50-25
=25cm.
y=80-50
=30cm.
From the principle of moment:
Sum of clockwise moment = Sum of anti-clockwise moment

60 * x=m * y
60 * 25 = m * 30
Divide both sides by 30
60 * 25/30 = m *30/30
m=60 * 25/30
m=2 * 25
m=50g.

How to Pass WASSCE Physics Practical Examination

Read the following tips carefully and get ready to make you WAEC with good grades.

Possess a Positive Attitude

It is self-evident that your life will not be positive until you have a positive perspective. You must have a good attitude about your fate as you prepare for WAEC.

Don’t utter things like “WAEC is incredibly difficult; I’m not sure if I’ll pass,” and don’t trust anyone who thinks you can’t pass WAEC 2022 on your own.

Have the mindset that “if others have passed WAEC 2022 in the past, then I will too.” Refuse to be associated with failure or those who have already failed.

Even if this isn’t your first time taking the WAEC Exam, it doesn’t mean you won’t pass WAEC 2022 physics practical this time.

With a refined attitude, sit for mathematics 2022/2023. Nothing will cause you to fail the WAEC 2022 examination. Your life will not be positive until you have a positive perspective.

Stay away from shady businesses

If you’re serious about passing WAEC physics 2022, stay away from bad firms. They will try to discourage you and get you involved in activities that will not help you succeed. Keep in mind that their mindset might not be the same as yours.

Make good goals and plans

If you’ve decided to pass WAEC Physics 2021, the next step is to create goals for yourself. Make a list of the grades you aim to get in WAEC 2022. You should start planning now if you want all As, no Fs, and no Es.

Make sure you have a time frame and a master plan in place to meet your objectives. It’s important to remember that it takes nothing to dream, but everything to focus on your dream.

Purchase the WAEC physics practical Recommended Manual for 2022

Obtaining the WAEC 2022 Physics suggested textbooks should be one of your goals. The West African Examination Council usually suggests literature for the exam.

However, except from WAEC 2022 English literature, where specified novels are required, you are free to utilize any decent textbook to study for the WAEC 2022 Accounting exam.

Some subjects are more difficult to grasp. If you’re having trouble understanding a topic, purchase a different textbook.

Download WAEC Physics Practical Past Questions and Answers

Are past questions really important? Yes, they are very important because it helps you in so many ways. First, some past questions appear in an exam as repeated questions. Secondly, they give vivid knowledge of how your exams will look like and the kind of questions you should expect.

Past questions give solid ground for you to practice. In that manner, I recommend you read WASSCE Practical questions and answers.
