A light spring is vertical and a mass less pan is attached to it. Force constant of the spring is k. A block of mass m is gently dropped on the pan. Plot the variation of spring potential energy, gravitation potential energy and the total potential energy of the system as a function of displacement (x) of the block. For gravitational potential energy take referece level to the initial postion of the pan.

(i) A block is connected to an ideal spring on a horizontal frictionless surface. The block is pulled a short distance and released. Plot the variation of kinetic energy of the block vs the spring potential energy. (ii) A ball of mass 200 g is projected from the top of a building 20 m high. The projection speed is 10 m/s at an angle theta=sin^(-1)(3/5) from the horizontal. Sketch a graph of kinetic energy of the ball against height measured from the ground. Indicate the values of kinetic energy at the top and bottom of the building and at the highest point of the trajectory, specifying the heights on the graph. Neglect air resistance and take g = 10 m//s^(2)

Energy: Kinetic Energy | Conservative and Non Conservative forces | Potential Energy (Gravitational and Spring) | Work energy theorem | Law of conservation of energy

Assertion: A spring has potential energy , both when it is compresed or stretched. Reason: In compressing or stretching, work is done on the spring against the resotoring force.
