Using a line integral to find the work done by a vector field example. Created by Sal Khan.
Math 2400: Calculus III Line Integrals over Vector Fields (c)Find a vector in the direction of the path that is travelled over a time inteveral of length t. Draw this vector on the graph as a typical short segment of the path. (Note that we are looking for r, and that r0(t) ˇ r t.) Solution:r0(t) = h 2 p 2sint;2 p 2costi.
14 maj 2021 · Q: calculate work done by force $F(x,y) = xy $ ${\bf i} + (y-x)\bf j$ over $c$ where $c$ is the unit circle. So this is what I did: since the curve is the unit circle then $x=\cos t$ and $y=\sin t$...
19 lis 2020 · One way to find the potential function is take the first component ($i$) of the vector field and integrate wrt $x$, similarly take the second component ($j$) wrt $y$. From there on, you should get the function.
Calculating work done when the force eld is not constant and the path is not linear. Now we'll nd the work done by a force eld F(x; y) = h y; p xi in moving an object along a semi-circular counter-clockwise path from ( 2; 2) to (2; 2) (the radius is 2 2). The force eld and the path are shown below. -3 -2 -1 0 1 2 3.
Explain what is meant by the vector projection of one vector onto another vector, and describe how to compute it. Calculate the work done by a given force.
