energy

1. ENERGY

3. Energy is the
capacity to do
work.
Unit of energy is
Joule

4. •Potential energy
•Kinetic energy
•Mechanical energy

5. Energy possessed by an
object due to its motion is
defined as kinetic energy.

6. Kinetic energy,
k=1/2mv2
M=mass and v is the
velocity of object

7. Potential energy is the
energy possessed by an
object by virtue of their
position.

8. U=Mgh,
where m is the mass of the
body,g is acceleration due to
gravity and h is the height of
body from earth.

9. Mechanical energy can
be defined as the sum
of kinetic and potential
energies of an object.

10. E=U+K where u is the
potential energy and k
is the kinetic energy

11. KINETIC ENERGY
 Energy possesed by a moving
ball
 Energy possessed by falling
water
 Energy possessed by a falling
stone

12.  Energy possessed by water in
dam
 Energy possesed by a stone
lying on ground
 Energy possessed by a book
lying in table
