Work and Potential Energy
The scalar product of a force F and the velocity v of its point of application defines the power input to a system at an instant of time. Integration of this power over the trajectory of the point of application, C=x(t), defines the work input to the system by the force.

Famous quotes containing the words work and, work, potential and/or energy:
“I must work, so as not to be a fool, to get on, to become a journalist, because that’s what I want!...

I must have something besides a husband and children, something that I can devote myself to!”

“Your children get a lot of good stuff out of your work...They benefit from the tales you tell over dinner. They learn from the things you explain to them about what you do. They brag about you at school. They learn that work is interesting, that it has dignity, that it is necessary and pleasing, and that it is a perfectly natural thing for both mothers and fathers to do...Your work enriches your children more than it deprives them.”
—Louise Lague (20th century)
“And what is the potential man, after all? Is he not the sum of all that is human? Divine, in other words?”

—James Madison (1751–1836)
