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

If the speed of body is halved, what will be the change in its kinetic energy?

If the momentum of a body is increased by 50%, then the percentage increase in its kinetic energy is

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?

In picking upan object from the floor and putting it on a table, we do work. However, the initial and final values ofthe object's kinetic energy are zero. Is there a violation of the work energy theorem here ? Explain why or why not.

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

If the velocity an object increases 4 times, its kinetic energy increases
