The total work done on any objects results in a total change in kinetic energy of that object. Net work done= final kinetic energy - Initial kinetic energy

In order to transfer energy to an object we need to exert a force on that object. And the amount of energy transferred by the force is called the word done by that force.

In order to transfer energy to an object we need to exert a force on that object. And the amount of energy transferred by the force is called the word done by that force. And formula for work done is the dot product of force exerted on that object and displacement by that object. Finally is replace F=ma and a=1/2mv^2. We will find that work done is the difference between the final and initial value of kinetic energy. And this is known as work-energy principle. read less

In practice, the sources of emf always have __________. (Zero resistance, unit resistance, some resistance, infinite resistance)
Internal resistance is always present with any practical energy source. If it is emf then internal resistance will be very low in series with the ideal emf source.

Respected tutors! I asked a question some time ago.My goal of asking question ,even after myself being a tutor, is to get clear with not so intuitive concepts, which i find intriguing. Q.What is the change in kinetic energy(ies) of body(ies) after collision of 2 moving bodies; you can take inelastic or elastic collision. 1- Remains same 2-Decreases 3-increases 4-any other possibilty All answers with 'decrease' options are correct, either elastic or inelastic collision. you can take any example and check. Q.Just think can KE be zero after collision? - this time its a bit more intuitive. Thanks.
it should remains same.. but if friction is taken into consideration then decreases would be the right option.
