When you lift a box from the floor and put it one an almirah the ptotential energy of the box increases, but thre is no change in its kinetic energy. Is it a violation of consevation of energy?

The total work done on a particle is equal to the change in its kinetic energy

The total work done on a particle is equal to the change in its kinetic energy

If the angular momentum of any rotating body increases by 200% , then the increase in its kinetic energy

A book is lifted from the floor and is kept in an almirah. One personn says that the potential energy of the book in increased by 20 J and the other says it is increased by 30 J. Is one of them necessarily wrong?

When kinetic energy of a body is increased by 800%, then percentage change in its linear momentum is

If the kinetic energy of a body increases by 0.1 % the percent increase of its momentum will be

You are reshelving books in a library. You lift a book from the floor to the top shelf. The kinetic energy of the book on the floor was zero and the kinetic energy of the book on the top shelf is zero, so no change occurs in the kinetic energy even though you did some work in lifting the books. Is the work-kinetic energy theorem violated?

Illustrate the law of conservation of energy by discussing the energy changes which occur when we draw a pendulum bob to one side and allow it to oscillate. Why does the bob eventually come to rest ? What happens to its energy eventually ? Is it a violation of the law of conservation of energy ?\

Potential energy changes into kinetic energy when it is put to use. True/False.
