OMG Thank you so much! I finally understand... no thanks to my useless physics teacher.

@pachenko92 Glad to help

Hi Mike. Great comment. Thanks for letting us know the videos were helpfull. Best of luck at university. We hope it goes well for you.

em... rulers and protractor to calculate answers for your vector acceleration question!? noooooooooooooooo... this is not awesome. this is garb. try attatching those two vectors tail to tail, then find the distance between those two head points using Cosine Law. Then, use your brain to figure out the exact vectors using Sine rule. Acceleration is V/T; so, get the accerlation value, and apply the vectors. This video is pure garbage

Hi.

I'm sorry you did not like this video. Our grade 11 students use graphing methods when first learning vectors so that they get a feel for what vectors are. Our grade 12 students would use cosine and sin laws to solve this but our intention was help those just starting to use vectors.

We have other videos that use algebraic methods, so please check those out.

Is there any video where you have to find the final velocity vector, following an acceleration vector that pushes the initial velocity vector to a new angle, so that you have to find the angle of the final velocity vector?

[PhysicsEH]

@chocolovemocha Hi. No, the initial veolcity is V1 and is 8m/s[E30N] and the final velocity is V2 and is 5m/s[E]. I hope that clears up your question.

I'm sure an "s" is used for displacement as D and d are already used so Yer wrong ye wee baw bag Advanced higher mofo ,

@HerlockSholmes123 I think you might be right. The angle 63.4 is written as [W 63.4 S] which is the same direction as [S 30 W] (with some rounding to 30). I get a triangle for the 5[E] + 8[W30S] that gives me components of 1.93 [W] and 4 [S] which makes a triangle to the left 1.93 and down 4 so the tan of the angle = 4/1.93 which gives you 64 degrees. I hope this helps.

thank you so much for this! YOU'RE VIDEOS really are a lot of help!!!

Helped a lot

@geekydude777 Chickens at rest stay at rest, chickens in motion tend to stay in motion. The chicken was obviously in motion in a vector in which the road could be transversed and particles of mass with opposing vectors of force were not encountered.
