    Answer:
    1. (a) Elastic
    (b) Potential
    (c) Gravitational
    (d) Kinetic
    2.( 500/1000)kg*1m*9.8
    =4.9J
    3. Both have same potential energy, because it does not depends on path.

    1)At A and D it has elastic potential energy, at B and C it has kinectic energy due to motion.
    2)5 J (in SI unit)
    3) both have same potential energy as potential energy depends only on height reached and not on the path taken.😊

      No the gravitional constant 9.8+0.5
      Hear 9.5 is constant
      And 500g is mass of the the book converted into 0.5kg
      Therefore 5.25 is answer

  • @dr.shwetakalra2765

    ANSWERS:
    1. Potential Energy and Kinetic energy
    2. PE=M×G×H
    PE=0.5 Kg(500g) × 10m/s²(Gravitational force on Earth is 10m/s²) × 1m
    PE=0.5 × 10 × 1
    PE=5 J
    3. Both the boys will have the same potential energy as both of them have the same mass. The path taken to reach the first floor does not matter. So, the height also remains the same. Both of them are on Earth. So, the gravity is the same.
    Thankyou!

    1ans)A) potential energy stored it it .
    B)potential energy converted into elastic potential energy due to change in it's configuration.
    c) elastic potential energy converted into gravitational potential energy due to change in it's position
    d)gravitational potential energy loses and gets converted into kinetic energy as velocity is produced .
    2.A)5 joules
    3) The potential energy is same in two bodies as they reached to same height

  • @magulongchannel1477
    @magulongchannel1477 3 роки тому +6

    The form of Energy are:
    1. Elastic potential to Combined Potential and Kinetic Energy going up, when it reaches the topmost part and has its sudden stop before dropping is Potential Energy, and while dropping it again acquires Potential and Kinetic Energy. Finally, when it lands and stop moving, its KE and PE are zero and assumes now Rest Energy.
    2. 5 Joules
    3. The boy who is in the escalator will reach the the first floor first and so his PE compared to the boy who took the stair will be more than the PE of the stair boy. however, when he also reached the same height of the escalator boy, both of them would have the same PE by then.

    (b) Potential energy as the ball is on a height.
    (c) Kinetic energy as it is falling
    (d) Potential energy as again it was on a height from the reference (i.e. the table)
    Answer 2 :(500g)(0.001kg)(10m/s^2)(1m)= 5 J
    Answer 3 :Both of them will get the same potential energy on reaching the top
    As potential energy depends on height to which a object reach not the way in
    which it come , if it comes to the same height as of th other one the potential
    energy will be equal of both of them.....

    If we had such teachers back then i would have been an engineer now. I chose science in my higher classes as i loved learning it.. Unfortunately in state boards our teachers only let us cram to score good because thats what actually matters in our education culture.
    I am preparing for competitive exams now for which i am watching your videos. I feel so bad kyunki science graduate hone k bavjuud bhi science se zyada acha hold i have in general studies ..... definitions sb cram hai equations etc..... lekin when it comes to practicals it is zero.

    q1:
    a, Elastic potential energy as the spring had the potential to create energy or work.
    b, gravitational potential energy as the ball was at a certain height.
    c, kinetic energy as the ball is in motion.
    d, kinetic energy as again the ball is in motion.
    q2: if i take the value of g to be 9.8 then answer is 4.9 joules = 4.9 j
    q3: According to the situation we know the height is directly proportional to potential energy so greater is the height greater is the potential energy but in this question it is not mentioned weather the stairs are at a greater height or the elevator, usually in a building both the stairs and the elevator are at the same height so we can say that since both have same height both will have same potential energy.

  • @blancaroca8786
    @blancaroca8786 4 роки тому +2

    Good videos! A couple of details:
    1. The gravitational potential energy is not exactly “inside” the hammer.. if we look inside it would be identical to before (elastic energy can be said to be inside the rubber band..looking inside the molecules will be adjusted in various ways). We can imagine some kind of invisible force field between Earth and hammer and so the gravitational energy is stored in this empty space between and nearby.
    2. The work energy done by the force depends on only the relatively small displacements of the projectiles meanwhile the force is acting when in contact with the pushing elastic, and is not related to the large distances moved by the projectiles. Once clear of the pushing elastic no more energy is given to projectile of course.

    1a - elastic
    1b - gravitational
    1c/d - kinetic
    2-5
    3-neither cause they are same

    a)Elestic potential energy into kinetic energy
    b)5 joules
    c)both has same potential energy because elevator has elastic potential energy and stairs has gravitational potential energy so they both are one type of potential energy
