    Relationship between kinetic and potential energy : When any mass is lifted, the gravitational force of the earth acts to bring it back down. The energy needed to lift up the mass is stored as potential energy due to its position. As the mass is dropped, stored potential energy is converted to kinetic energy. mg(h - x) + 1/2 mv^2= mgh

    When a bird takes left or right turn it does not remain horizontal but tilts like a plane. Thus pressing the air with greater area of the underside. As per Newton's Third Law of Motion the air underneath also exerts equal and opposite force on the bird, like normal force on a banked circular road. The horizontal component of this force is the required centripetal force for the bird.Read more on Sarthaks.com - https://www.sarthaks.com/300103/bird-while-flying-takes-left-turn-where-does-it-get-the-the-required-centripetal-force-from

    It is constant .. think that if acting the force on wall then the work is zero and momentum is zero because that object can't travel some distance and the force is constant .. here the force is zero then body not travel distance.... jb force hi ni lagega toh momentum kaha se change hoga iss ley woh constant hai

    Harsh Mishra 6 years, 4 months ago

    Examples of Newton's II nd  Law of Motion are :-

    • If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.
    • It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.

    Thanks Harsh a lot but i know the answer ....I'm just freshing up my mind....nothing else??

    3Thank You

    Harsh Mishra 6 years, 4 months ago

    Let the force be F,
    Mass is M,
    Time for which it is accelerated = 2 second,
    Velocity is increased from 3 m/s to 7 m/s
    So, acceleration is , a = (7-3) / 2 = 2 m/s²
    Therefore, The force applied is, F = ma = (5)(2) = 10 N

    1.this method gives us no. information about the dimensionless constants in the formula. Ex 1,2,π,etc 2.if a quantity depends on more than three factors, having dimensions.,the formula can't be derived 3.we can't derive the formula containing trignometrical functions, exponential functions, log functions etc which have no dimensions 4.it gives no information whether a physical quantity is scaler or vector

    Here, the error is added because is in addition.

    In parallel combination, the reciprocal of the resistances are added.

    After we differentiate the parallel combination formula we get,

    We need to keep the error on one side and bring the rest on another side.

    On rounding, we get,
