What Is Physics Practical Specimen
Before I proceed to the major focus of the post, I would like to let everyone reading this article to understand the real meaning of specimen and their applications.
I hope that you may have been taught about the meaning of specimen and what they are used for in your respective secondary schools, but this is another opportunity to let it come afresh in your memory in case you have forgotten it.
For those of you have not been taught about specimens, guides and their applications in physics in your schools, you do not have to worry much since you have finally come across the information that I have for you in article.
I hope that you take this article very serious and maximally utilize the information contained therein.
A Physics practical specimen can be said to mean an entity, object or non-living thing or part taken to exemplify or represent a mass of whole number which can serve the same purpose.
Physics practical specimen represents any matter or apparatus that can be used for the purpose of conducting any physics-related experiments. For the purpose of this article, I shall be focusing on the kind of specimen used in the WAEC physics practical.

Guides On How To Answer Physics Practical Questions
Answering physics practical questions is a special practice that every WAEC candidate should not overlook. It requires specific principles that you must follow if you must get the expected results. Here, I am going to guide you on how to answer physics practical questions at any level
Contrary to the general assumption that Physics practical is one of the toughest subjects to write in WAEC, I want to let you know that it is not even tough at all. It only requires the application of some of the basic principles that I am going to show you here.
Also, let me reassure you that it very much possible to write physics practical on your own, without any form of malpractices and you will still make an ‘A’ comfortably.
Follow me as I guide you on the following eye-opening principles that will guarantee your success in WAEC Physics Practical examination:
Study Your Specimens
It is absolutely impossible for anyone to excel in any practical examination with a prior study on the given specimen. As a WAEC candidate, once you are preparing for the practical examination, the aspect that you should pay a kin attention to is everything about the given specimens.
Even in the examination hall, you have to be able to identify the specimens that have been provided for you. Not only that, you should also be able to understanding the application(s) of any provided specimen.
Usually, more than one specimen is given for the purpose of WAEC Physics Practical. A good understanding of the specimens will reveal to you how each of the specimens is related with one another in terms of applications during experiments.
By studying the specimens, you will provide the required answers to the physics practical questions and that will guarantee your excellent performance at the end of the examination.
Read the Practical guideline
You will be provided with practical guidelines during the WAEC Physics Practical examination. Before you proceed with the experiments, make sure that you read the guides carefully so as to follow the right steps from the beginning to the end.
There is no need rush into the practical when you have not understood the practical guideline.
Adhere to Instructions
This is one of the areas that most students get WAEC Physics Practical questions wrong. That you have seen a similar question before should not cause you to delve into answering physics practical questions with a previous knowledge only.
You still have to read and follow strictly to any given instruction during your physics practical examination. In addition, do not assume that WAEC is wrong based on the instruction given, and you will start to be doing another thing.
Make sure that you follow WAEC Physics Practical Instructions strictly.
Report you Practical Works Accurately
Giving accurate report of your practical work is very crucial to your success in the WAEC Practical examination. It is very possible for a candidate to understand what he/she is doing during the examination but not know how to report the work accurately.
Poor presentation of practical report is one of the major setbacks which cause most students to have poor performance in WAEC physics examinations.
It is highly advisable to be conversant with the procedure for reporting WAEC Physics Practical answers even before you get into the examination.
Always be Careful While Handling Apparatus
Almost all the apparatus used in practical, especially Physics and Chemistry are very fragile and delicate to handle. As such, you have to be extremely careful while handling the apparatus during the examination to avoid damaging any of the provided specimens.
Remember that the West Africa Examination Council (WAEC) is not going to give any special consideration to any school that could not complete their experiments due to any damage that happened during the examination.
To avoid this damage, ensure that you read the precautionary measures that are required for every experiment in Physics. Also, take time and study all the necessary laboratory ethics before the date of the examination.
Learn How to Set Up Apparatus
As a science student, one of things that you must also learn before any practical examination is how to set up practical specimen and apparatus, without which, you are not going to get expected result in all your experiment.
Arrange Your Work Very Well
The arrangement of your works matters a lot in every examination. Some of the arrangements that you have to take cognizant of while reporting practical works are Page margin, your numbering pattern, the alignment of your works, your clarity and so on.
You should also take note that in your answer booklet, there is always a part of the margin that you are not expected to write on. You have to adhere to this rule and any other regulation that related to it.
Manage your Time
Time management is also very important. Usually, time that is allotted to WAEC Physics Practical Examination is not always enough for an amateur candidate.
However, if you are able to manage your time very well, you can still finish the examination with the limited time and you will still have enough time left to summarize and revisit you works.
Use the Right Unit
The most important consideration while taken experimental reading in all science subjects is the S.I. Unit. Once your unit is wrong, your answers that are affected will be termed wrong answers.
For the sake of any science examination, you have to consciously learn all the commonly used S.I. Unit of measurements.
Units of Measurement
The following are some of the commonly used S.I. Units in Physics:
| Physical Quantity | Units |
| Time | Second (s) |
| Mass | Kilogram (kg) |
| Distance | Meters (m) |
| Heat | Joule (J) |
| Current | Ampere (A) |
| Voltage | Volt (v) |
| Velocity | Meter per second (MS-1) |
| Acceleration | MS-2 |
| Speed | MS-1 |
| Density | Kg/m3 |
| Area | M2 |
| Energy | Joule (J) |
| Impulse | NS-1 |
| Work | Joule (J) |
| Pressure | N/m2 |
| Force | N |
| Momentum | Kgm/s |
| Volume | M3 |
| Temperature | K |

TABULATE:
| S/N | M(g) | X(cm) | X-1(cm-1) | X-1(10-3) |
| 1 | 40.00 | 37.50 | 0.027 | 27.00 |
| 2 | 60.00 | 25.00 | 0.400 | 40.00 |

| 5 | 120.00 | 12.50 | 0.080 | 80.00 |
Note: G=50.0cm Y=30.0cm
(1a)
(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 x Perpendicular distance of its line of action from the point
Moment = F x D
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 x 25 = m x 30
Divide both sides by 30
60 x 25/30 = m x 30/30
m=60 x 25/30
m=2 x 25
m=50g.
