We will see in this section that work done by the net force gives a system energy of motion, and in the process we will also find an expression for the energy of motion.Let us start by considering the total, or net, work done on a system. Net work is defined to be the sum of ...
Work and Kinetic Energy – The Work-Energy Theorem Consider an object with an initial velocity ‘u’. A force F, applied on it displaces it through ‘s’, and accelerates it, changing its velocity to ‘v’. Its equation of motion can be written as: v2 –u2 = 2as Multiplying this ...

The work function can be experimentally determined by measuring the maximum kinetic energy of the emitted electrons and using the equation: work function = energy of incident photon - maximum kinetic energy of emitted electron. This can be done using techniques such as photoelectric spectroscopy or ...
The net work on a system equals the change in the quantity. The quantityin the work-energy theorem is defined to be the translationalkinetic energy(KE) of a massmoving at a speed. (Translationalkinetic energy is distinct fromrotationalkinetic energy, which is considered later.) In equation for...

Derivation of Kinetic Energy Formula The derivation of kinetic energy formula is given below: Kinetic energy = Work done = F x s……….(1) By third equation of motion, v2–u2=2asv2–u2=2as s=v2–u22as=v2–u22a………(2) By Newton’s second law of motion, F = m x a ………...
TheSI(International System of Units) unit of Kinetic energy is Joule(Kg.m2.s-2)and in CGS (centimeter–gram–second system), it is defined in terms of erg(10-7Joule or gm.cm2.s-2) Kinetic energy equation Thework-energy theoremstates that the total work done on a system is equal to...
From equation (1), (2) and (3) W=ma*(V²-u²/2a)\=(1/2)m(V²-u²) As the object in a state of rest, u=0 W=(1/2)mV² Furthermore, the kinetic energy of a body moving with a certain velocity is equal to work done on the object. This work is for the purpos...
