Potential energy and work done by a charge are directly related. The work done by a charge is equal to the change in its potential energy. This means that when a charge moves from one point to another in an electric field, its potential energy changes and work is done. ...

When work is done by many forces acting on a body, the kinetic energy of the object changes. The total work done by all the forces appears as change in kinetic energy of the object, which is the statement of work-energy principle.Answer and E...
The work done by non-conservative forces is equal to the total change in kinetic and potential energy. True or False? Without friction or work by an external force, the sum of the potential and kinetic energies of a body is constant. a. True. b. False....
Could I say that the total energy of a system is the sum of the work of all force + kinetic energy ? I'm always confuse on which force gives a potential or not... But maybe at the end, it's just the sum of work of each force ? newtonian-mechanics forces energy work potential-...
If we define Potential Energy U as Mm 1 2 U g = mgy U u = −G0 U s = kx 2 r Then, Wconser = −∆U The work done by a conservative force = minus increment of “U” related to the force (保守力作功等 于该势能增量的负值) 于该势能增量的负值). Descriptions: 1. “U”...

Kinetic Energy Energy can exist in many forms: heat, light, nuclear energy, chemical energy (from food or fuel), stored (potential) energy (such as the energy stored in a compressed spring) and so on. Energy can be transferred from one form to another and can be used to create motion....
Electric Potential Energy: The electric potential energy is the potential energy associated with the electric field. At any point, the electric potential energy is defined as the amount of work done against the electric field in bringing a unit charge from a ref...
