3. DIFFERENT WAYS BY WHICH
OBJECTS CAN POSSES ENERGY
Potential Energy
Kinetic Energy

4. POTENTIAL ENERGY
The energy possessed due to position or
strain
Potential Energy ,
U = mgh
m = mass
g = acceleration due to
gravity
h = height

5. Example of Potential
Energy
Energy present in the water stored at a
height

6. KINETIC ENERGY
Energy possessed by an object due
to its motion
Kinetic energy, K = ½ mv^2
m = mass
v = velocity

7. Example of Kinetic energy
Water flows down through
penstock pipe
