For those who struggle with finding the direction of the resultsnt force, just remember it is between the 2 forces that are given in the diagram always
You "invent" your own scale. you get better at it with practice. You want to choose a scale that allows your diagram to "fill" the allotted space without overflowing it. You do't want your diagram to be too small. Begin with 1 cm = ... . If the vector is a 100 km vector and you have about 10 cm to fill, then choose the scale that 1 cm = 10 km. This will make the vector 10 cm long.
@@PhysicsclassroomVideos Would these scaled diagrams normally be used to solve an equation graphically? When you're attaching the head of of the first vector to the tail of the second?
@@PhysicsclassroomVideos So when we cancel out the cm (assuming the scale is 10m=1cm) and we multiply the displacement, by 10m, we would then factor in the third vector?
140m/s 200 degrees Scale:1cm=20m How do you find the length of these vector? 140m/s divided by 20m is 7cm?? Am I right?🥺 what about the units?? They will not get cancelled

Thanks. This helped me alot. Keep helping others!.
Good. Helping others is what its all about!
Could you pls try 1cm=10 m/s??? Pls??? CCW dir'n and it's magnitude?
this is so helpful thank you
thanks a lot, saved my life!
THank you!!!

How do we determine the scale?

@@aunmaqsood3129 yes ... or to resolve graphically (less common) in order to determine the components.
How do we determine the scale ...that my main problem
How would you use vector scale diagrams, with three displacements, to find the singular value?
The third vector gets added to the end of the second vector.

How do you get 11 cm?
The scale of one cm represents 2 m/s is used. The vector 22 m/s would be 11 cm long according to the scale. Thats 22÷2 = 11.
How did you arive from the 11 cm lenght of the vector at the end part?? Please help
At about 6:40 ... Scale is 1 cm = 2 m/s. Divide 22 m/s by 2 m/s and get 11 cm.
140m/s 200 degrees
Scale:1cm=20m
How do you find the length of these vector?
140m/s divided by 20m is 7cm?? Am I right?🥺 what about the units?? They will not get cancelled
@@geann6570 scale should be 1 cm = 20 m/s ... the the units work out.
Okay thank you...please keep more on making videos..thanks for your responsive replies..very much appreciated...
You helped a lot🥰👏
May i ask how to draw vector to scale without direction like for example 50 km/h
How woukd you draw 5mm to scale withoit direction?
How to draw vector into scale diagram if there's no indicated direction?
I need your help asap
As the video explains, create a scale - like 1 cm = 10 km/hr - then draw a 5 cm long vector with an arrowhead on the end.
What would be its direction?is it EAST?
May you please help in calculating displacement using a vector scale diagram?
It works the same way as described in the video.
