Physical Science

1. Energy Production and Management

2. ENERGY the capacity to perform tasks. When work is accomplished, energy is moved from one entity to another. Energy comes in various types, such as electrical and chemical energy.

3. Kinetic Energy vs. Potential Energy Kinetic energy pertains to the energy of objects in motion. Objects with kinetic energy possess the ability to perform tasks. The amount of kinetic energy is dependent upon the object's mass and speed. Potential energy denotes the energy stored within an object due to its specific position or shape.

4. SOURCES OF ENERGY

5. 1. FOSSIL FUEL It refers to buried, flammable geologic deposits of natural elements that decomposed under conditions of high pressure and temperature. EXAMPLES: Crude oil (such as octanes, C8H18) natural gas or biogas (CH4) coal (C)

6. 2. Biogas Biogas is a gas that results from the anaerobic (without oxygen) breakdown of organic materials. A biogas digester was built as an alternative energy source in Batangas City in locations like Lipa. Methane gas used for cooking was successfully produced, which could meet the needs of the neighborhood.

7. 3. Geothermal Energy (Earth-heat) It refers to the heat created inside the Earth, clean and sustainable. It has been around for whatever length of time that the world has existed.

8. 4. Hydrothermal Energy It refers to the heat obtained from hot water from hydrothermal vents or seawater in contact with hot rock beds. Two types of energy can be harnessed from the ocean. A. Heat energy from the sun B. Mechanical energy from the waves and tides

9. 5. Hydroelectric Energy Moving water is used in hydroelectric power plants to turn turbines. This produces around 45% of the region's power, making it the primary source in Mindanao. Most hydroelectric power plants have three main components: a water reservoir a gate or valve that regulates the amount of water that flows out of the reservoir an outlet or location where the water goes after flowing downstream.

10. MAGAT HYDROELECTRIC PLANT

11. 6. Biomass It refers to organic material. Life is related to the term organic, so biomass is consisting of composed of organic matter., most of which are a waste product. Since biomass is from organic waste, here are some of its sources Composting materials - consist of combined decaying plants or food products Wood - it could be a source of biomass since it is a sample of organic material. Municipal and City wastes - the organic waste product after garbage segregation

12. BIOMASS

13. 7. Solar cells They are devices that can absorb light energy from the sun and convert it into electricity. The most common material in solar cells that causes the PV effect is Silicon, the main substance in beach sand. Utilizing Solar Cell as the Energy Sources Light energy is collected over solar panels that are used for domestic purposes and only take around 20% of the sunlight that they receive and turn it into electricity. The collected energy can be stored in batteries or can be directly converted to electricity (solar efficiency).

14. 8. Batteries They are devices that store and convert chemical energy into electrical energy. They can be disposable or rechargeable. The energy from batteries comes from a chemical reaction (e.g. redox reaction between CuSO 4 and Zn to form ZnSO 4 and Cu). The energy is stored on the lithium-ion battery which is the most suitable energy storage device for powering electric vehicles (EVs).

15. 9.Wind Power The energy from the wind is being harnessed by the wind turbines, converting the wind energy into mechanical energy. This kind of energy is renewable since the wind on the surroundings is unlimited.
