Webb2 mars 2015 · What we’ll calculate is the energy gained by an object that starts at rest, is pushed by a force F (x) over a distance D, and moves from position x=0 at time t=0 to position x=D at time t=T. When we say the object started “at rest” we mean “v (0)=0”. Whatever v (T) is, it’s the velocity of the object when we’re done.
