The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in …

NettetIf it takes 4 J of work to stretch a Hooke's law spring 10 cm from its unstretched length, determine the extra work required to stretch it an additional 10 cm. Solution: Reasoning: The work done in stretching or compressing a spring is proportional to the square of the displacement. If we double the displacement, we do 4 times as much work.

Work done when lifting an object at constant speed

NettetThe work done on a point mass is done by a heavier gravitational force. It is common physics notation to denote work as negative when a system does work on itself and to denote work as positive when a an external force does work on the system. Also, point masses move objects from an higher potential to lower potential energy. http://labman.phys.utk.edu/phys135core/modules/m6/Hooke
