@@brightnwandire1706 increasing the masses does not have any effect on the period of oscillation. Hence the idea of increasing the masses will not work. You can try it out for yourself
They have asked this question in previous year. I believe there must be a way to use the masses in this experiment. Why do they now request two 10g, two 20g and two 50g?
Yeah, you are right. Actually, I counted correctly. The error there is the time lag during my video editing. I'm sorry about that. Thanks for your observation.
Yes the formula will work depending on how WAEC decides to construct the question for the experiment. That's why there's a delay from me to do the cheat.
The table of values is not the problem, because what Waec checks out on the table is whether the values follow the specified trend. They are more interested in the value of your slope.
Yes you're right, and that's what I did. Due to the nature of it's oscillation, the fro movement is usually faint. Your eyes misjudged my counting. But that's a nice observation 👍. Thanks
@@sellaxi Well in like another practical could you like do a physics practical past question on an actual graph to so ic could see what it should look like like where to put precautions cause like most times during exam I usually feel like i've literally plotted like a good graph and then if the practical takes ike 50 marks i end up getting like 34 and i want get into the 40's if not the 50's please🙏
Very nice video how did you manage to solve for r2 s2
🥵🥰
Thanks
Thanks sir,God bless you.I pray that in point of your need ,God will send you an helper.Amen
Amen
Expect more videos tomorrow
Please share to your friends
Amen, please share the video
Thank you so much
You're welcome 😊
This video is well explained
Thanks sir
Thanks
Brilliant! Well done sir.
You're welcome
Thanks
Awesome video, sir please how did you get 0.88
Thanks
Pls isn't the ruler suppose to go back and front before recording one oscillation?
Exactly. He's doing 10 oscillations
Wow. This is great. What software did you please use for the graph?
Thanks sir
Nice vids real quick...can the ruler be set into to and fro oscillation
The direction of oscillation has already been given, about a vertical axis through the center of gravity
@@sellaxi thanks can this formula be used to manipulate the experiment without carrying it out T=2π×(√L/g)
Yeah, I think so.👍
Tried, but let's try and predict base on what is provided, 2 ten gram masses, 2 20gram masses and 2 50gram masses. What happens to these other once?
This practical is really very interesting. I'll be making a video explanation on what to expect from WAEC in this practical soon.
Job well done sir.... Please do u work at Hallel College
I'm no longer at Hallel College. I was a physics teacher there once. Please are you a student of Hallel?
Anyway, help me share the video. Thanks
@@sellaxi yes I was 😅
I hope u kw that we are giving various masses... Mass can be varied while d height can be constant have u tried that
Varying the masses has no effect on the period of oscillation
I believe that WAEC will have a way to deal with those masses or, in fact they won't all be used. I happens at times

I thought not all the points will allign with the graph
Sometimes not all
I don't understand the reading.
I thought the rule will go and come back to it mean position before taking it as one oscillation.
Yeah, you are right. Actually, I counted correctly. The error there is the time lag during my video editing. I'm sorry about that. Thanks for your observation.
@@sellaxi thank you
Thanks for the good job sir,will there be cheat video on this ??
Sure
@@sellaxi can I use this formula for the cheat T=2pie sqrt L/g
Yes the formula will work depending on how WAEC decides to construct the question for the experiment. That's why there's a delay from me to do the cheat.
@@sellaxi but will it work for this particular experiment sir?
Yes
Kudos, sir well appreciated, in d exams normally there is Alt A and B, if dis one is for A, are u gonna make a video for Alt B pract.
If you want me to do it, I'll
@@sellaxi but I thought alternative B was not for Nigeria??
Pls does waec provide permanent marking scheme for physics practicals or they mark ur paper based on your table
There's marking scheme for physics practical
@@sellaxi does waec provide table of values or the paper is marked with ur table of values or ranges are given
The table of values is not the problem, because what Waec checks out on the table is whether the values follow the specified trend.
They are more interested in the value of your slope.
Is the count for one oscillation not supposed to be the to and fro movement?
I noticed you counted the number of oscillation as it goes to and fro
Yes you're right, and that's what I did. Due to the nature of it's oscillation, the fro movement is usually faint. Your eyes misjudged my counting. But that's a nice observation 👍. Thanks
Any cheat for this practical please
Except it soon
I don't understand please
Please where exactly do you more clarification?
I meant to say is there any practical cheat for this 2021 practical
@@sellaxi any cheat sir
WAIT WHAT ARE THINGS THAT TAKE AWAY MARKS IN PHYSICS PRACTICAL
When you don't have a good table of values, and when you forget to include the units of measurement where necessary

@@richardtheaspiringanimator Well, that's a sincere comment, alright I would do that .
@@sellaxi THANKS
Okay, well noted

whos writing their physics practical today?
