Question
Work from force How much work is required to move an object from $x=0$ to $x=3$ (measured in meters) in the presence of a force (in N) given by $F(x)=2 x$ acting along the $x$ -axis?
Step 1
In this case, the force is given by $F(x)=2x$ and the distance is from $x=0$ to $x=3$. So, the work done is given by the integral: $$ W=\int_{0}^{3} F(x) dx = \int_{0}^{3} 2x dx $$ Show more…

Work from force How much work is required to move an object from $x=1$ to $x=3$ (measured in meters) in the presence of a force (in $\mathrm{N}$ ) given by $F(x)=\frac{2}{x^{2}}$ acting along the $x$ -axis?

How much work is required to move an object from x = 1 to x = 7 (measured in meters) in the presence of a constant force of 4 N acting along the x-axis? The work required is
How much work is required to move an object from x = 2 to x = 9 (measured in meters) with a constant force of 3 N acting along the x-axis? If a constant force F displaces an object a distance d in the direction of the force, what is the correct relationship to use to calculate the work done? A. work = force ∙ distance B. work = force - distance C. work = force / distance D. work = distance / force The work required is J.
