Ch. 25 Using Calculus with Physics
... Velocity is the derivative of displacement with respect to time. The slope of the tangent to the line of a graph of displacement vs. time is the velocity Work is the integral of force as a function of displacement times displacement. The area under the curve of a graph of force vs. displacement is t ...
