In physics, a conservative force is a force with the property that the total work done by the force in moving a particle between two points is independent of the path taken. [1] Equivalently, if a particle travels in a closed loop, the total work done (the sum of the force acting along the path multiplied by the displacement ) by a conservative ...
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 addition to the force they could apply, leading ...
The force field experienced by the one moving on the staircase is non-conservative in that one can return to the starting point while ascending more than one descends or vice versa, resulting in nonzero work done by gravity.
The current problem isn’t hard to understand: In the absence of major reforms, the U.S. government will, for the foreseeable future, spend significantly more on entitlement programs and interest ...
Project 2025 is a policy plan for a conservative president created by a think tank. It includes 900 pages of radical ideas for federal government. What is Project 2025?
Musk has reveled in the chaos, even wielding a chainsaw at a conservative political conference last week. The chief of Tesla and social media platform X has said he aims to cut $1 trillion from ...
The work done by the force F is given by the integral = = = = = , where dr is the differential element along the curve that is the trajectory of P, and v is its velocity. It is important to notice that the value of the work W depends on the trajectory r ( t ) .
Work is dependent on the displacement as well as the force acting on an object. As a particle moves through a force field along a path C, the work done by the force is a line integral: = This value is independent of the velocity /momentum that the particle travels along the path.
