  • The work energy theorem defines the relationship between the idea of work and energy. I discuss work and energy and their relationship, including how potential and kinetic energy is defined.
    It includes how the formulas are derived.

    when an object is moving in uniform velocity, the work done is 0 right?

    Nice sir, from 🇮🇳india, until it's position remained constant, was it in balanced equilibrium?

    Isn't there work done in the first example because of counteracting static friction? If not why not

      Until it moves there is no work done. It’s no different to pushing a wall.

    If a object moves with a uniform velocity that means there is no acceleration, then work is done 0 but in the book,work =1/2mv^2. But why?.Please explain it sir.

      Work done changes KE. So the object had to start at zero velocity. So work done is it’s increase or decrease in KE

    Why there are dislikes,
    that disappoints.

    You can also do work on an object if you change its shape e.g. crushing an aluminium can.

    • @PhysicsHigh

      That is true. I essence you are causing displacement on parts of the can.

      @@PhysicsHigh I realised a minute after I posted this that this ties in with thermodynamics i.e. the relationships between pressure, volume and temperature in ideal gases... Carnot cycle etc.

    Can you make a video on Newton's second law
