4. *INTRODUCTION OF
MODEL*
Our model is illustrates the phenomenon of
MECHANICAL ENERGY CONSERVATION.
LAW OF ENERGY COSERVATION- Energy can
neither be created nor destroyed , but it can be
converted from one form to another.
Total mechanical energy = K.E.+P.E.
5. Energy at point A = Energy point B
• P.E.A + K.E.A = P.E.B + K.E.B
• We assume that height at A is h1
and at B is h2 and mass of ball is
m.
• mgh1+1/2𝑚𝑣2
= mgh2+1/2m𝑣2
• h1 = h2
