3. I-DEFINITION/CHARACTERISTICS
Mechanical Energy-is the energy
possessed by an object due to its
motion or its stored energy at
position.Mechanicalenergy can be
either kinetic (energy of motion) or
potential energy (energy of
position).Mechanical energy is energy
stored in objects by application of a
force.

4. The wrecking ball possesses potential
mechanical energy when it is raised to a
vertical position above the ground.

5. WHAT MAKES CARS GO?
Moving parts hooked up the engine
called drivetrain. The drivetrain
carries mechanical energy from the
engine to the wheels. The turning
wheels make an automobile go.

6. Thermal Pollution-discharge of heated
liquid into water.
How it Transformed?
The heat is absorbed by the surrounding
material causing it to raise its
temperature.This is easily felt in factories
using huge machines using energy.When
these machines are in operation,the air
temperature increases.This condition in
energy may develop into thermal
pollution.
Into the Future:Science and Health

7. Accelerate the exploration and development of renewable
energy resources such as, but not limited to, biomass,
solar, wind, hydro, geothermal and ocean energy sources,
including hybrid systems, to achieve energy self-reliance,
through the adoption of sustainable energy development
strategies to reduce the country's dependence on fossil
fuels and thereby minimize the country's exposure to price
fluctuations in the international markets, the effects of which
spiral down to almost all sectors of the economy;
IV-Application-(Philippine
Setting)
Biomass energy systems" refer to energy
systems which use biomass resources to produce
heat, steam, mechanical power or electricity through
either thermochemical, biochemical or physico-
chemical processes, or through such other
technologies which shall comply with prescribed
environmental standards pursuant to this Act;

9. Let's do an experiment with mechanical
energy. If you are watching this video on
somemobile device like laptop, go ahead
and lift it about six inches from its present
position. Congratulations! You just
demonstrated mechanical energy. So
don't let anyone tell you that you didn't
accomplish any work today. The force
generated by your muscles moved the
device, and that's work. Don't overexert
yourself. You can put the device back
down now.

10. THANK YOU FOR LISTENING AND WATCHING
