WORK AND ENERGY CBSE Class 9

WORK AND ENERGY
  • Work is said to be done on a body when non-zero
    force acting on it displaces it in the direction
    of the applied force. When the direction of
    applied force and that of the displacement of the
    object are the same, the work done on the object
    is said to be positive.
  • When the direction of the applied force and that
    of the displacement of the object are opposite to
    each other, the work done on the object is said
    to be negative. Work done on a body is said to be
    zero, if the non-zero force acting on it produces
    zero displacement.
  • Energy is the capacity of an object to do work.
    There are various forms of energy such as heat
    energy, electr rical energy, kinetic energy,
    potential energy etc. Kinetic energy is the
    energy possessed by a body by virtue of its
    motion. Potential energy is the energy possessed
    by a body by virtue of its position or
    configuration.
