A freely falling stone possesses K.E and P.E.

For a freely falling body

What is a freely falling body ?

What is the nature of the graph between K.E. and P.E. of a particle performing a finear S.H.M. ?

A particle executes SHM on a line 8 cm long. Its K.E. and P.E. will be equal when its distance from the mean position is :-

A body of mass m suspended from a spring executes SHM. Calculate ratio of K.E and P.E. Of body when it is at a displacement half of its amplitude from mean position.

The KE of a freely falling body

Potential energy of a body is the energy possessed by the body by virtue of its position. P.E. =mgh where the symbols have their usual meaning. Kinetic energy of a body is the energy possessed by the body by virtual of its velocity. K.E.=(1)/(2)m upsilon^(2) Energy can neither be created nor be destroyed. However energy can be changed from one form to other, such that energy appearing in one form is equal to the energy disappearing in the other form. With the help of the passage given above, choose the most appropriate alternative for each of the following question : The body will attain this K.E. when it falls freely from a height of
