dear tushan,
The work done by the resultant force acting on a body is equal to the change in its kinetic energy.

Relation bewteen KE and W: The work done on an object by a net force equals the change in kinetic energy of the object: W = KEf - KEi. This relationship is called the work-energy theorem.
rahul kushwaha
For any net force acting on a particle moving along any curvilinear path, it can be demonstrated that its work equals the change in the kinetic energy of the particle by a simple derivation analogous to the equation above.calls by the name of work energy theorem.....

To change the kinetic energy of a particle we have to apply a force on it and the force must do work on it. This relationship between KE and WORK is called "work -energy theorem "...[W=KEf-KEi]
Pranav Dabhade
work done by all forces =change in K.E it can also written as,[W=KEf-KEi] .That means kinetic energy lost is converted inti work &vice a versa.,

The amount of work done by the net force acting on a particle is equal change in it’s kinetic energy.

work energy therom is nothing but the total work done by all forces is equal to the change in its kinetic energy …. W=1/2 {kx22-kx12}

Total workdone by the Net Force on the body is equal to change in it’s kinetic energy.
Wtotal=1/2{kx22-kx12}

The work W done by the net force on a particle equals the change in the particle`s kinetic energy KE: W = Δ K E = 1 2 m v f 2 − 1 2 m v i 2 . The work-energy theorem can be derived from Newton`s second law. Work transfers energy from one place to another or one form to another. thank you

The work-energy theorem is a generalized description of motion which states that work done by the sum of all forces acting on an object is equal to change in that object’s kinetic energy. This principle of work and its relationship to kinetic energy is a core mechanical physics concept.
The work-energy theorem describes direct relationship between work and energy, its formula shows that net amount of work done by forces acting on a particle causes a change in that particle’s kinetic energy.
Work is an action that is performed on an object or system and that transfers energy from one location or from one form to another. Basic formula is work = force x distance
Kinetic energy is the energy of motion that an object or system has at a given point in time. Basic mathematical formula is kinetic energy = ½* mass * velocity².
Since work = energy, formulas for each can be substituted to create following work-energy equation: force * distance = ½ * mass * velocity². This equation is transformed into a set of other equations called ‘kinematics equations’.
The work-energy theorem can be derived from Newton’s second law of motion, which concerns inversely proportional relationship between acceleration and mass and directly proportional relationship between net force and acceleration.

It states that,”the work done by application of a force on a body equal to the change in kinetic energy of a body.”
Ragini
Acc to this theorem the work done by constant force is equal to the change in KE or increase. in KE.......

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
