Question

A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.
The work done on the box is ____ Nm, and the power is ____ Nm/s.

Answer 1

Work done=F.d

Power= work/time

Answer 2

As in: Work done in the direction the force is applied

\(dW = \vec{ F} (\vec{ x}) \bullet d \vec{x}\)


So

\(W(\vec{ x}) = \int_C \vec{ F} (\vec{ x}) \bullet d \vec{x}\)
