THREE NATURAL

EXAMPLES

(Written or images)

Electrical

·         Through the mobility of the electrically charged particles (electrons), Electrical energy is obtained.

·         The faster the mobility of the particles, the more electrical energy.

·         Once the charged particles are mobile, the electrical energy is in kinetic energy form.

 

·         Residential uses: quite several households of the world today are electrically powered. They use electrical energy in their daily activities such as computing, water heating, refrigeration, etc.

·         Industrial uses: factories and industries consume huge amounts of electricity in driving the manufacturing process.

·         Transportation: electrical energy is used in mass transit systems and electric vehicles.

·         Hydroelectric plant

·         Nuclear power plant

·         Solar Panels.

 

·         Wind energy

·         Electric eels

·         Lightning

Chemical

·         It is the energy that is stored in chemical compounds including atoms and molecules.

·         In a chemical reaction, there is the bond breaking of atoms resulting in energy being realized.

·         Once chemical energy is released from a substance for example dry wood, the wood is turned into a new substance (ash).

 

·         In food, we consume chemical energy. The bond breakage of food atom, there is a chemical reaction taking place and a new compound is formed. During this reaction, energy is produced thus the energy enables us to walk, enhances growth, and keeps us warm.

·         In the burning of wood, chemical energy is liberated in form of heat. The energy is then converted to heat and light energy which might be purposeful in body warming, cooking, and light energy for seeing clearly.

 

·         Batteries.

·         Vehicle airbags.

·         Charcoal

·         Petroleum

·         Natural gas

·         Coal

Sound

·         As force is applied to a substance, there is the vibration of particles of the substance causing sound that is transmitted through waves

·         Sound energy cannot be transmitted over the vacuum as there is no medium for transmission, unlike light energy.

·         It’s applicable in medical fields to perform ultrasound treatment for cancer treatment and tumors, detection of heart complications, and detecting developmental abnormalities of the fetus in mothers.

·         Used mineral and petroleum exploration, oil-bearing rocks beneath the water.

·         Guitar

·         Screaming

·         Talk

 

 

·         Thunderstorm

·         Ocean tides

·         Earthquake.

Nuclear

·         Nuclear energy is the energy stored in the nuclei of atoms.

·         The voluminous amount of energy can be produced when the nuclei are fused or split.

·         The fusion and fission of the uranium atom result in heat production which in turn heats water into steam which spins the turbines to produce electricity.

 

 

 

·         During the fission of Uranium in the reactor of the nuclear plant, heat is generated and heat is used to heat water to steam that in turn spins the turbines hence producing electricity.

·         The byproducts during fission such as cobalt-60 are used in the sanitization of hospital equipment such as scalpels, implants. The cobalt-60 is also useful in radiotherapy for medical screening treatment and diagnosis of cancer.

·         Nuclear energy is also used in food treatment and agriculture. For example, in agriculture, it is used in sterilizing pests and limiting pesticides usage while in food treatment, nuclear energy is used to test foods and sterilize harmful contaminants on food products.

·         Nuclear power plant

 

·         Sun

·         Fission

·         Fusion

 

 

Thermal

·         Thermal energy is also referred to as heat energy.

·         It is a type of energy that results when atoms and molecules of a substance vibrate.

·         Heat speeds up the movement of the particles and the faster the movement of the particles within an object, the higher the temperature recorded

·         Production of liquid fuel through hydrolysis

·         Drying of agricultural products before storage

·         Applicable in the generation of electricity which is widely used for household and industrial activities

·         Baking an oven

·         Boiling kettle

·         Fire

·         Sun

·         Magma

 

Mechanical

·         Is the energy possessed by an object when at rest or in motion?

·         It can either be potential energy(possessed energy at rest) or kinetic energy(possessed in motion ).

·         It’s applicable in motors to turn wheels.

·         It enables our body to work

·         windmills

·         cycling

·         pulley

·         Breathing in and out

·         Moon rotation

·         Asteroid.

Gravitational

·         It’s an energy an object possesses about its position in a gravitational field.

·         Gravitational energy is enhanced when the position of the object is closer to the center of the earth.

·         It’s applicable in writing (pen and paper)

·         Comfortability in sitting, walking, and standing

·         Water flow in taps

·         The pendulum

·         Roller coasters

·         skateboard

·         Pulling of water to the bottom of the dam

·         Force holding gases in the sun.

·         Force cause ball was thrown on air to come down

·
