...effort curve Mean effort Length of effort curve SUMMARY OF CHAPTER III. The work done by a force upon a body is measured by the product of the force and...the body moves in the direction of the force. The unit is the foot-pound. The work depends only on the initial and final positions of the body and not... | |

...kinetic energy may now be defined as the product of the total force exerted on a Ixxly and the element of distance through which the body moves in the direction of the force : dE = Fds. Since both the force and the motion pertain to a particular body, the kinetic energy does... | |

The work done by a force acting obliquely on a mooing body is measured by the product of the force and the distance through which the body moves in the direction of the force.
