- Chad provides a comprehensive lesson on Relative Motion and how to solve relative motion physics problems involving relative velocity in one and two dimensional motion. He begins with a couple of 1-dimensional relative velocity problems, the classic relative motion train problems. Whether these trains are moving in the same direction or in opposite directions, the relative velocity between the trains can be calculated to determine how long it takes for the trains to collide. He uses these relative motion problems in 1-dimenstion as a good introduction to relative velocity in 2d problems for which he covers a classic problem involving a swimmer crossing a river (identical in concept to the classical relative velocity riverboat problems). Once again, Chad demonstrates that the x-dimension and y-dimension can be treated independently in 2-dimensional motion problems including relative velocity in 2d problems.

chad i hope to be as knowlegable as you one day you are my king
🙂 You can do it!
Premium content 👌
Kind words - thanks!
TYSM! Hope you post some videos about MCAT test especially the CARS part.
Regarding the last question. Won't the swimmer have to swim along the hypotenuse of the triangle theirby making the travel longer?
I was curious about this too
i love your videos man keep up with the good content
Thanks - Glad you think so!
Why is it 3 sin theta and 3 cos theta
Was the answer 56 degrees the answer to the question "What was his velocity relative to an observer on shore while crossing?" Or was the answer 3.6 m/s? I was confused. Thank you~
