Unit: Work, energy and power (Hindi)

Physics for Computer Science Students pp Cite as. The terms work, energy, and power are common words in English. In physics we require precise definitions so that these terms can be formulated mathematically. Readers will find that definitions in physics do not always match the usage of the words. For example, although a student may do homework, by the physics definition of work none is being done, although at the biological cellular level, chemical work is being done. We will not consider chemical work in this book. It is important that we consider mechanical work, energy, and power, for it is the treatment of these terms from First Principles that will be applied directly to electrical circuits.

Question 6. The sign of work done by a force on a body is important to understand. State carefully if the following quantities are positive or negative: a Work done by a man in lifting a bucket out of a well by means of a rope tied to the bucket, b Work done by gravitational force in the above case, c Work done by friction on a body sliding down an inclined plane, d Work done by an applied force on a body moving on a rough horizontal plane with uniform velocity, e Work done by the resistive force of air on a vibrating pendulum in bringing it to rest. Compute the a Work done by the applied force in 10 s b Work done by friction in 10 s c Work done by the net force on the body in 10 s d Change in kinetic energy of the body in 10 s and interpret your results. Given figures are examples of some potential energy functions in one dimension.
