The document discusses different types of mechanical energy and energy in general. It defines mechanical energy as the energy an object has from its motion or potential for motion. It then describes two main types of mechanical energy: 1) potential energy, which is the energy an object has due to its position or ability to do work, such as a stretched rubber band or rock on a cliff, and 2) kinetic energy, which is the energy associated with an object's motion, such as a moving bicycle. The document further discusses different types of energy in matter, including gravitational, chemical, elastic, electrical, and nuclear energy. It also defines kinetic energy and lists some examples of kinetic energy forms.

3. •The ability to do work.

4. Mechanical Energy
The energy an object has from its motion or
its potential for motion.

5. 1. Potential energy.
The energy an object
has as a result of its
position or ability to
perform work.
A stretched rubber
band, compressed air,
or a rock sitting on the
top of a cliff all have
potential energy.
2. Kinetic energy.
The energy specifically
associated with an
object’s motion.
A bicycle or
skateboard in motion
possesses this form of
mechanical energy.
Mechanical Energy

6. Energy in matter due to arrangements of its parts, its composition, location
and structure. It is commonly considered as a stored energy having the
potential to do mechanical work.
1. Gravitational Potential Energy (GPE). Energy stored in an object’s
position.
2. Chemical Energy. Energy contained inside substances.
3. Elastic Energy. Energy contained in an stretched object.
4. Electrical Energy. Energy from the movement of electrically charged
particles.
5. Nuclear Energy. Energy obtained from the Fusion and Fission of
Nuclei of atoms.

7. Energy in matter due to arrangements of its parts, its composition, location
and structure. It is commonly considered as a stored energy having the
potential to do mechanical work.

8. B. Kinetic Energy
- Energy in moving matter and wave.
1.Motion. Energy from moving objects
2.Radiant. Energy from rays and waves
3. Sound. Energy from vibrations
4. thermal. Thermal energy is a form of kinetic
energy and is transferred as heat.

11. where
KE= ½ mv KE = Kinetic Energy
m = mass of the object
v = velocity of object

12. Transformation of Energy
•LAW OF CONSERVATION OF ENERGY
•Definition: This states that energy can change
from one form to another, but it cannot be
created or destroyed.
•Important: When energy is used, it does not
disappear……it simply changes to another
form.
