1. Energy Transformations
#energy #transformation #science #ngscience
In what ways can energy be converted from one form to another? Let's take a look.
Head to NGScience for related worksheets and other resources on energy for use in the classroom and at home.
Energy is all around us. We can't see energy, but we can see the things that energy does. Energy makes things move. It powers the machines we use. It can make things get hotter or produce sound. Energy is used to light up our homes and cities and power the vehicles we use. Plants and other organisms need energy to live, grow and carry out life processes.
Energy cannot be created...nor can it be destroyed. But it can be changed ... or transformed... from one form to another and we can observe this happening around us every day.
Let's take a look at some examples. As each video plays, write down the energy transformations you think are taking place. We'll go through each example at the end so you can check your answers. Let's go.
1. What energy transformation takes place when a ukulele is strummed?
2. What energy transformation takes place when a light bulb is switched on?
3. What transformation takes place when a match is struck?
4. What transformation takes place when a drawn bow and arrow is released?
5. What transformation takes place when an electric kettle is switched on?
6. What energy transformation takes place when a roller coaster rolls down the track?
7. What transformation takes place when an electric doorbell is pressed?
8. What energy transformation takes place when drill is used to secure a screw into wood?
How'd you go...let's take another look.
When a ukulele is strummed, kinetic energy is transformed into sound energy.
When a light bulb is switched on, electrical energy is transformed into light and heat.
When a match is struck, kinetic energy and chemical energy is transformed into light and heat.
Ehen a drawn bow and arrow is released elastic potential energy is converted into electrical energy.
When an electric kettle is switched on, electrical energy is transformed into heat.
When a roller coaster rolls down the track, gravitational potential energy is transformed into kinetic energy.
When an electric doorbell is pressed electrical energy in transformed into kinetic energy and sound.
When drill is used to secure a screw into wood, electrical energy is transformed into kinetic energy.
Take note that in many of the examples provided, heat and sound are also often produced.

5. TYPES OF ENERGY | Physics Animation
Hello, Learners! This is EarthPen. Today, we are going to talk about another fun topic in Physics. It is all about the types of energy.
Energy can be categorized into two broad topics; kinetic energy and potential energy. These two are the basic forms of energy. And we know that kinetic energy is the energy of moving objects while potential energy is energy that is stored. But aside from these two energies, there are also other types of energy. This includes thermal energy, radiant energy, light energy, chemical energy, nuclear energy, electrical energy, gravitational energy, and mechanical energy.
Let us discuss them one by one.
The first type of energy that we’re going to discuss is thermal energy. Thermal energy or also called heat energy is produced when there is a rise in temperature that causes atoms and molecules to move faster and collide with each other.
But how is thermal energy produced? Thermal energy is the energy that comes from the heated up substance which means that the hotter the substance, the more its particles move, and the higher its thermal energy.
To better understand this, let us have an example. Say you have a hot pot. You forgot that the pot is hot so you grabbed it with your hand. Now, your hand is burnt because of the hot pot. The thermal energy from the hot pot is being transferred to your hand that is why you felt the burn in your hands. So, better be careful when dealing with hot things.
The next type of energy that we’re going to discuss is radiant energy.
What is radiant energy? Radiant energy is a form of electromagnetic energy. This type of energy can take the form of visible waves, which is what we call light energy. But we’ll be talking about light energy later.
The sun produces a lot of radiant energy which is transmitted to Earth as light. Radiant energy that is transmitted by electromagnetic waves can come in different forms. Some examples of radiant energy are from the sunshine, x-rays, and radiant heating systems.

8. Conduction -Convection- Radiation-Heat Transfer
Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion.
In this video, I focus on three ways heat can be transferred,
Conduction, Convection, and Radiation.
Conduction involves direct contact between objects and usually occurs among solids.
Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source.
Radiation occurs without objects touching and occurs in space.
For example, the energy of the sun warms objects on Earth due to radiation.
I show several examples or demonstrations for each type of heat transfer.
9. Energy | Forms of Energy | Law of Conservation of Energy | Science Lesson for Kids
In this video, we will learn about energy, its two types and forms.
What is energy?
Energy is defined as the ability to do work, which is when a force is applied to an object and it moves.
Energy is divided into two types, POTENTIAL ENERGY AND KINETIC ENERGY.
Potential energy is the energy stored in an object.
Kinetic energy is the energy that a moving object has.
Energy is measured in Joules (J).
Forms of Potential Energy
1. Chemical Energy
2. Elastic Energy
3. Nuclear Energy
4. Gravitational Energy
Forms of Kinetic Energy
1. Mechanical Energy
2. Electrical Energy
3. Thermal Energy
4. Light Energy

What Is Thermal Energy?
All matter is made up of tiny particles. Whether matter is in a solid, liquid or gas, these particles are always in motion. How much these particles move is called thermal energy.
The more thermal energy matter has, the higher its temperature. Temperature is how hot or cold matter is. It is a measure of the average kinetic energy of the particles in matter. The faster the particles mover, the greater the temperature.
When matter gains thermal energy, the particles that make up the matter move faster. Its thermal energy increases and its temperature also increases. When matter loses thermal energy, the particles that make up the matter move slower. Its thermal energy decreases and its temperature decreases.
So how does matter gain thermal energy? The movement of thermal energy is called heat. Heat occurs whenever there is difference in temperature.
Let’s look at an example of the heat that occurs when a hot object comes in contact with a cold object. In both objects, the particles are moving – they have kinetic energy. When the objects are touching, their particles collide with each other. As they collide, the hot object passes energy to the cold object. The hot object gets cooler and the cold object gets warmer. Heat will continue to move in this way until the temperature of both objects is equal.
When you place a cold metal spoon into a hot cup of tea, energy moves from the hot tea to the spoon. The tea loses thermal energy and gets cooler. The spoon gains thermal energy and gets hotter. The metal spoon will continue to gain thermal energy from the hot tea until the temperature of the tea and the spoon are equal.
Just as heat moves from hot to cold between objects, it also moves in this way within objects. Let’s look at an example of placing a metal rod over a fire. The heat from the fire will cause the particles at the tip of the rod to gain thermal energy and its temperature increases. These particles then collide with the particles adjacent to them. In this way, heat in transferred from the hot region to the cold region of the metal rod.
Thermal energy moves in three main ways – conduction, convection and radiation.
Think again how heat moved in the metal rod placed on a fire. The thermal energy moved from the hot part of the rod to the cooler part of the rod. This movement of heat within an object is called conduction. Conduction also occurs when objects are touching. If you were to hold the cool end of the rod, before too long it would feel warm as thermal energy moves by conduction to your hand.
Heat transfer from a hot cup to your hands and cooking a piece of fish in a pan are also examples of conduction.
Liquids and gases are similar in that they have no fixed shape. They are fluids. Thermal energy can be transferred from one region of a fluid to another due to movements within the fluid. This movement of thermal energy, called convection, is caused by hot parts of the fluid rising and the cooler parts of the fluid sinking.
Think about the water in a kettle as it is heated. The water touching the heating element is heated by conduction. The water becomes warm and rises. As it does so, the cooler water sinks and a current is created within the water. The current causes the thermal energy to spread through the water in the kettle.
The heating of air in a hot air balloon is also an example of convection.
For thermal energy to move by conduction and convection it must travel through matter. Between the Sun and the Earth is empty space. How does the heat from the Sun warm the Earth and other planets in the solar system? The answer is radiation. Radiation is the transfer of energy through electromagnetic waves.
The warmth you feel when you place your hand near an electric heater or a campfire are examples of heat in the form of radiation.
