I have a practical test considering that tumorrow .l hope l will pass but without saying to much l would like to tell you that you are the best physics teacher in the world😚
Good day sir, please I need a confirmation on something, I was told in my senior year that line of best fit must pick at least 2-3 points but yours didn't pick any, so I'm confused
1)How to plot the graph of M against e? 2) measure the slope and explain its physical meaning. State the unit and estimate the error. 3) Did your graph pass through the origin? If not, give reasons. Deduced from your load(mass) extension, graph the weight Wa of the given object A.
Based on the scattering of the points the line of best fit may not be on all the points. You'll want to get as many points as possible on the line with an event distribution on both sides
Yes it's possible. If the values on the x axis is larger than those on the y, you will get a decimal for the gradient. Ensure you also include the unit for your gradient
Sir! if we need to plot 31.8 on a scale of 1unit =5cm then how do we plot that point between 30 and 35? How to start counting from 30 onwards to find 31.8 between 30 and 35?
It would be slightly below the second small line after the line for 30. Each small line represents 1 based on the scale you used. I'm assuming the scale you used is 1 cm = 1 unit
Technically no. It all depends on how the points are scattered. The objective is to have an even distribution of points about the line of best fit. Thanks for watching
12:32 Why is it that you drew the broken lines above the 1.59 and not through it and you drew the vertical line at 0.75 instead of 0.7 on the x axis. Why didn't you draw the line through the last point?
Good observation. The reason why I drew the lines above 1.59 and .7 is to ensure that I get my points as far apart as possible. The line didn't go through the last point because the objective was to get the best fit line which shows and average of all the points plotted. Let me know that clears it up
Also when I am choosing my points I will tend to choose the most reasonable points that meet the criteria of being far apart and also not found in the table.
@@realJuniorRoberts Ok but why draw the second point above at 0.7 (y axis) but then draw the vertical line through the marked point at 0.1 on the x axis?

Once you have an equal distribution of points on both sides. When drawing best fit line it's best to use a clear ruler so you can see where the line would fall between the point
I’m in grade 7 and the y axis and x axis numbers are whole numbers but we are given decimals to put the points I honestly don’t understand and the teacher not explaining😭
Yes plotting decimals can be a bit challenging. When plotting decimals you can use whole number scales but have to be careful in identifying the values that you have to plot. This video should help you with plotting decimals. If you're still having challenges let me know

2) measure the slope and explain its physical meaning.
State the unit and estimate the error.
3) Did your graph pass through the origin? If not, give reasons.
Deduced from your load(mass) extension, graph the weight Wa of the given object A.
Estimate the error in Wa.
I really enjoyed the video
Thank you for watching
Pls sir, is the line of best fit not supposed to be on the points
Based on the scattering of the points the line of best fit may not be on all the points. You'll want to get as many points as possible on the line with an event distribution on both sides
This video helps a lot.

Sir can i ask??? What is the difference between 0.1 and 0.01 scale/ increment? Thank you
The difference between both is that one increases by 0.1 while the other increases by 0.01
@@realJuniorRoberts Thank you sir God bless
@@jaybheart9767 you are most welcome. If you have other questions you could let me know
Good job❤ very helpful
Sir, what if we are told to plot 4.98,4.95,4.96 , 5.03,5.06,5.09 as such ? How should I take the scale ?
Could you send the entire data set you have to plot?
Hi, I tried to construct the graph my self and my gradient is 0.057. Is it possible for your gradient to be 0. something?
Yes it's possible. If the values on the x axis is larger than those on the y, you will get a decimal for the gradient. Ensure you also include the unit for your gradient
@@realJuniorRoberts ok thanks so much

It would be slightly below the second small line after the line for 30. Each small line represents 1 based on the scale you used. I'm assuming the scale you used is 1 cm = 1 unit

@@jayaneepanchal1614 you are most welcome 🙏🏾
So, the line of bestfit doesn't have to go through a point?
Technically no. It all depends on how the points are scattered. The objective is to have an even distribution of points about the line of best fit. Thanks for watching
Is there a systematic mathematical formula to calculate scale. I have a hard time guessing. Any help is appreciated
Yes there is a systematic approach. Watch this video for help ua-cam.com/video/CYnVesLm8vo/v-deo.html. Thank you for watching 🙏🏾🔥
Sir please what does 2cm to rep 1unit in a graph means?
Each bold block measures 1cm so in this example it means that for each two bold blocks the scale on the axis increment by 1 unit
Let me know if that helps

@@realJuniorRoberts Ok but why draw the second point above at 0.7 (y axis) but then draw the vertical line through the marked point at 0.1 on the x axis?
Why not put it at 0.7y, 0.05x?
@@Kris_413 again to keep the points far apart and also choosing that point was quite easy to read off from the line
Csn you choose anywhere to be your gradient
Yes you can use points anywhere on the best fit line. Ensure they are far apart and does not correspond with plotted points

Sir what if you are plotting 0.10 till the end value and 0.3,0.5,0.9,1.20 and 1.50 how will that be sir
You'd be able to plot those using the same approach seen in the video. If you need further clarification you could let me know

How to draw the line ? How to know where the average of the point?
Once you have an equal distribution of points on both sides. When drawing best fit line it's best to use a clear ruler so you can see where the line would fall between the point
