Lesson Worksheet: Work and Integration Mathematics

Complete the following: If a force given by acts in the direction of the positive , then the work done by the force in moving a particle from to , where equals .

True or False: If an object moves along a straight line by a varying force , then the work done to move the object from to is given by .

The figure shows the magnitude of a force acting on a body as it moves a distance . Given that the force is measured in newtons and the distance is measured in meters, determine the work done in joules by the force to move the body from to .

A body moves along the -axis under the action of a force, . Given that , where m is the displacement from the origin, determine the work done on the body by when the body moves from to .

A variable force , measured in newtons, is acting on a body, where . Find the work done by this force in the interval from to .

A body moves along the under the action of a force . Given that , where is the displacement from the origin, determine the work done on the body by when the body moves from to .

A particle moves in a straight line under the action of the force , where and is measured in meters. Calculate the work done by the force when the particle moves from to .

A block moves in a straight line under the action of a force , where meters is the displacement of the body from its initial position. The work done by the force in moving the block from to is 34 J. Determine the work done by in moving the block from to .
