Question

Explain how you would determine how much error there is between a vector addition and the real results.
Using what you have determined to be the best method, develop a unique example and calculate the resultant displacement between two points when there are two legs or distinct parts to the trip. Include the displacement of each leg of the trip as well as the resultant displacement of the entire trip.
Don't forget: include both the direction and the magnitude as part of the displacement

I'm having trouble with these two question. Please help I need to finish this worksheet by tomorrow please help.

Answer 1

link/post the original question :-)

Answer 2

Post 1: Explain how you would determine how much error there is between a vector addition and the real results.


Responses 1 and 2: Critique other students' posts by agreeing with their method and explaining why it is superior to yours, or suggest why another proposal is superior to theirs. Respond to at least two posts.

Response 3: Using what you have determined to be the best method, develop a unique example (not posted on the discussion board by anyone else) and calculate the resultant displacement between two points when there are two legs or distinct parts to the trip. Include the displacement of each leg of the trip as well as the resultant displacement of the entire trip.
Don't forget: include both the direction and the magnitude as part of the displacement.

This is how the the question is originally.

Answer 3

i mean, literally, post what you are looking at .

or answer it yourself !!

Answer 4

This is what i am looking at that is all of it

Answer 5

seems i am too dumb. sorry. i did read it all.

Answer 6

@osprey

i mean this thing

Answer 7

@teenage_kicks19 i have tagged someone else

good luck

Answer 8

thank you

Answer 9

This is a guess.
About the only example I can think of of "vector addition and the real results", as the post puts it, is the demonstration of the "equilibirium of 3 coplanar forces" using three laboratory masses and three bits of string and two pulleys and a KNOT. The thing is rigged up so that the knot is static under the "neutralised influence" of the weights of the the three masses as in "coplanar forces".
Then, I think that you trace out the lines and the knot on some paper which is already behind the rig. (A drawing board, or some other thing like it might/prob would help). The idea is to match up the sketch you make on the paper with the "theory" of vector combination given that you want equilibrium.
Risking a complete mess on the floor if the thing went wrong, it MIGHT be possible to put some tension spring balances in each "arm" of the rig of strings, to obtain some measure/reading of the forces which they say are acting on the knot.
It's a sort of 3-d "tug o'war".

I recognise the words in this post, but I don't really see how they fit together. Above is my best interpretation of the first sentence with some sort of answer.

The thrust of the second paragraph seems to be that a vector is a quantity with magnitude and direction.
Just pondering before I go to press, direction can be measured with a protractor, either the "school kit" version or one with a Vernier scale on it for increased headaches/precision/accuracy. The magnitude presumably depends on what the vector actually IS. A temperature gradient vector would, I think, be a lot harder to measure for magnitude than the tug o'war mentioned above.
