Question

Identify the correct statement about work energy theorem:
(A) work done by all the conservative forces is equal to the decrease in potential energy
(B) work done by all the forces except the conservation forces is equal to the change in mechanical energy
(C) work done by all the forces is equal to the change in kinetic energy
(D) work done by all the forces is equal to the change in potential energy

Answer 1

Hint In some times, the people will forget which the work energy theorem will apply only to the network, but not the work done by the single force. The work energy theorem states that the total work done by the force of an object is equal to the change in the definite energy.

Complete step by step solution
The guideline of work and dynamic energy (otherwise called the work-energy hypothesis) expresses that the work done by the amount of all powers following up on a molecule approaches the adjustment in the motor energy of the molecule. This definition can be reached out to unbending bodies by characterizing crafted by the force and rotational motor energy.
In material science, work is the energy moved to or from an article by means of the utilization of power along a removal. In its least difficult structure, it is frequently spoken to as the result of power and uprooting. A power is said to accomplish positive work if (when applied) it has a part toward the removal of the purpose of use. A power accomplishes negative work in the event that it has a part inverse to the heading of the dislodging at the purpose of utilization of the power.
The determination of the work–energy rule starts with Newton's second law of movement and the resultant power on a molecule. Calculation of the scalar result of the powers with the speed of the molecule assesses the quick force added to the system. Requirements characterize the bearing of development of the molecule by guaranteeing there is no part of speed toward the imperative power. This likewise implies the limitation powers don't add to the immediate force. The time fundamental of this scalar condition yields work from the prompt force, and active energy from the scalar result of speed and quickening.

Hence, the option (C) is the correct answer.

Note This segment centres around the work–energy rule as it applies to molecule elements. In more broad frameworks work can change the likely energy of a mechanical gadget, the warm energy in a warm framework, or the electrical energy in an electrical gadget. Work moves energy starting with one spot then onto the next or one structure to another.
