    About the Lecture

    The lecture Work: As Change in Energy by Jared Rovny is from the course Work.


    Included Quiz Questions

    1. It loses kinetic energy, gravity does negative work
    2. It loses kinetic energy, gravity does positive work
    3. It gains kinetic energy, gravity does negative work
    4. It gains kinetic energy, gravity does positive work
    5. Its kinetic energy remains unchanged because energy is conserved
    1. It was converted by work into gravitational potential energy
    2. It was converted into work according to the work-energy theorem
    3. By conservation of energy, it is unchanged
    4. It is converted into the heat of the air molecules around it
    5. It has changed the direction of its initial kinetic energy, using work
    1. The total work done on an object is equal to its change in the kinetic energy
    2. The total work done on an object will equal its change in total energy
    3. The work done by a particular force will be equal to the change in kinetic energy of the object, even if there are other forces
    4. The work done in a particular direction will be equal to the change in the amount of energy in that direction
    5. The work done on an object will be equal to the amount of potential energy it loses
    1. The force of gravity is opposite the motion, work is negative, kinetic energy is lost
    2. The force of gravity is with the motion, work is negative, kinetic energy is lost
    3. The force of gravity is opposite the motion, work is positive, kinetic energy is lost
    4. The force of gravity is opposite the motion, work is positive, kinetic energy is gained
    5. The force of gravity is with the motion, work is positive, kinetic energy is gained

    every concept is made very simple and as short as possible
