Understanding conservative force ... In order to understand the perspective of conservative force, we consider a block of mass "m", which is projected up a smooth incline. Here, interactiion involves gravitational force. The force due to gravity, opposing the motion, is mg sinθ along the incline.

Conservative Forces are reversible forces, meaning that the work done by a conservative force is recoverable, i.e. you can get out any work you put in or vise versa.

Idea: It is not always true that the work done by an external force is stored as some form of potential energy. This is only true if the force is conservative:

What is the physical distinction between a conservative and a non-conservative force-field? Well, the easiest way of answering this question is to slightly modify the problem discussed above.

Potential energy is the energy of position resulting from any conservative force. ... Potential energy is the energy resulting from an object's position when it is acted on by a conservative force. Kinetic energy is the energy of motion. The sum of the potential and kinetic energy of an object is its mechanical energy.

If a force acting on an object is a function of position only, it is said to be a conservative force, and it can be represented by a potential energy function which for a one-dimensional case satisfies the derivative condition...

is: a force which is not a conservative force, so that there is no unique potential energy at each point and the work that it does between two points is dependent on the path chosen. [P2.4] ... is exemplified: by frictional forces and muscular forces. [P2.4]

Marxism agrees that religion is a conservative force, although it is not a positive force or valuable to society. Marxism says that religion is used to reproduce, preserve and legitimise class inequality; it is seen as an 'opiate of ...

A conservative force field is defined as one for which the net work done on an object in a closed path is zero. That is, the force field is conservative if ... where the path of integration is arbitrary. The scalar function is referred to as the potential of the conservative force in question. If the function is known...
