Answer to: Find the work done by the force field F(x, y) = xsin(y)i + yj on a particle that moves along the parabola y = x^2 from (-1, 1) to(2, 4)....... Show transcribed image text To calculate the work done by a force. If an external force, F, acts on a rigid body, the work, U_F, done by the force when it moves along a path s is defined as U_F = integral_r F middot dr = integral_s F cos theta ds where theta is the angle between the force and the object's direction of motion and r is the

**Work Done By Gravitational Force Equation For**

Net work is defined to be the sum of work done by all external forcesâ€”that is, net work is the work done by the net external force . In equation form, this is where is the angle between the force vector and the displacement vector. how to potty train a cairn terrier puppy Looking at the graph, it's easy to see that the area under the curve is a triangle. Using basic geometry, we can find the amount of work done by simply calculating the area of the triangle.. How to start a blog about patchwork

## How To Find The Work Done By A Force

### I know that work = force x distance. However, what vector operation should I do? I was wondering whether I should possible find the unit vector of r and then use the dot product leaving the answer as a multiple of n where n represents the number of units of distance traveled.

- Calculate the work input in a pulley by using the previous readings in the correct mathematical equation: Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height traveled (h). Using these physics equations you can calculate the work input/work output of any pulley system.
- Find the work done by the force field in moving the particle from one point to another. Ask Question 2. 1. Find work done by the force field F in moving the particle from $(-1, 1)$ to $(3, 2)$ This sounds good till we are given that $\textbf{F} = \dfrac{2x}{y}\textbf{ i }- \dfrac{x^2}{y^2}\textbf{ j }$ Can someone explain how to understand this problem, does the word conservative field have a
- Preliminary Information: To explore the definition of work and learn how to find the work done by a force on an object. The word "work" has many meanings when used in everyday life.
- Calculate the work needed to lift a 90N block of ice a vertical distance of 3m. what PE does it have? 90(3)=270=300J When the same block of ice is raised the same vertical distance by pushing it up a 5m long inclined plane, only 54N of force is required.
