What is mass energy equivalence?
The mass-energy equivalence theory states an object at rest in a frame of reference has a rest energy. If additional energy is supplied to the object, it actually increases that object's mass. For example, if you heat a steel bearing (adding thermal energy), you very slightly increase its mass.
What is the law of conservation of energy?
According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form. Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat at the point of collision.

All electromagnetic waves can travel at the same speed, the speed of light, which is about 186,000 miles per second!
What is potential energy?
Potential energy is being stored, ready to do work. If a pencil is resting on the table, it has potential energy. If it falls from the table, that potential energy has been changed into kinetic energy, the energy of motion (with a boost from the kinetic energy of whatever gave it a push).
Where does nuclear energy come from?
Nuclear energy comes from fission, the splitting of atoms, or fusion, the joining of atoms.
Where is chemical energy stored?
Chemical energy is potential energy stored in the chemical bonds that join atoms together. It can be converted to electrical, heat, or other energy through chemical reactions that break the bonds. Food is a source of chemical energy. Our bodies store the potential energy until we need it.
Is electromagnetic radiation a wave?
Since the electromagnetic spectrum is also made up of photons, it can act as either a stream of particles or as a wave. EM radiation is made of electrical fields and magnetic fields together. Each type of EM radiation has different wavelengths and frequencies. Frequency is the number of waves in a given time.

Hence, heat transferred may become thermal energy, while work done may manifest itself in the form of mechanical energy. All forms of energy are associated with motion. For example, any given body has kinetic energy if it is in motion.
What are the two types of energy?
Science classifies energy into two categories – kinetic (moving) and potential (stored) energy. Kinetic or moving energy. Potential or stored energy. Electrical energy – the movement of electrical charges. Everything is made of atoms, which in turn are made of a positive nucleus surrounded by negative electrons.
What are some examples of elastic energy?
Elastic energy – objects that are stretched or squashed have had a force applied to them and store energy from that force. Examples include springs and rubber bands. Sound energy – a wave that moves out from a source as a result of molecules on an object vibrating.
What is kinetic energy?
kinetic energy: The extra energy of an object that it possesses due to its motion.
What is the energy that is used to make the sound and the picture on the TV?
When we eat food, our body uses (chemical) energy embodied in the food to move around. When we switch on the TV, electricity ( kinetic energy) is used to create the picture on the screen and the sound. Most of the electricity produced in the world comes from the chemical energy released in the burning of coal, oil or gas.
How does energy work?
Let’s look at a few examples of energy use: 1 When we eat food, our body uses (chemical) energy embodied in the food to move around. 2 When we switch on the TV, electricity ( kinetic energy) is used to create the picture on the screen and the sound. 3 Most of the electricity produced in the world comes from the chemical energy released in the burning of coal, oil or gas.
What is sound energy?
Sound energy – a wave that moves out from a source as a result of molecules on an object vibrating. Chemical energy – stored in the bonds that hold atoms together, and when the bonds are broken, energy is released (and will become kinetic energy. Motion/kinetic energy – the energy an object possesses because of its motion.
What is the transfer of energy in materials from the random movement of the particles in that material?
Heat energy (heat): Heat energy: the transfer of energy in materials from the random movement of the particles in that material. The greater the random movement of particles the more heat energy the material has. Temperature is a measure of the heat energy of a material.
When is energy used?
Energy is present whenever there are moving objects, sound, light, heat, or electricity. In all those cases, energy is moving from one place to another.
What are the forms of energy we can store?
we can store it in various forms—with chemicals, thermal energy, gravitationally, etc.;
What is the kinetic energy of an object?
When an object is moving, like a baseball or a car, we say it has kinetic energy, i.e., energy of motion. Just how much kinetic energy the object has depends on its mass and its speed. For two objects with the same speed, the more massive object has more kinetic energy. So a car going 50 MPH has more energy than a baseball going 50 MPH. If two objects have the same mass, then the faster object has more kinetic energy.
How is energy transferred from place to place?
How energy is transferred from place to place is the one instance where NGSS mentions different types of energy: Energy can be transferred from place to place by sound, light, heat, and electric currents. Energy can also be transferred from place to place by objects in motion. But notice that it doesn’t refer to those as different forms of energy, just different ways that energy can move from one place to another.
What is conservation of energy?
Conservation of energy is one of the most important principles in all of science. It means that energy cannot be created or destroyed; it can only change form. The expression “produce energy” really refers to the conversion of stored energy into a desired form for practical use. Here’s a kind of thinking game you can play with your students. Whenever you have some energy, you can always ask about where it came from. For example:
Where does energy travel from?
A: From sunlight! Energy travels from the Sun to the Earth in the form of light, and when the corn was growing, it stored some of that solar energy (as chemical energy, thanks to photosynthesis).
Is energy a substance? (no) Is it real?
A: You can probably guess that there’s not a simple answer to that question. A physicist might say that energy is the ability to do work, although that doesn’t tell us what energy really is. Is it a substance? (no) Is it real? (yes) And because it’s so hard to define, many teachers will instead just describe some of the characteristics. That’s very similar to how we discuss “life”—without actually defining it. Since there’s no universally agreed upon definition of life, we usually instead talk about the “characteristics of life,” living vs. nonliving things, and the different kinds of life. In the same way, rather than actually defining energy, teachers often talk about the characteristics of energy and different kinds of energy, although, as we’ll see, memorizing different types of energy isn’t what’s really important.
What is energy in everyday life?
Energy is a word which tends to be used a lot in everyday life. Though it is often used quite loosely, it does have a very specific physical meaning. Energy is a measurement of the ability of something to do work. It is not a material substance. Energy can be stored and measured in many forms.
Why is it called potential energy?
It is called potential energy because it has the potential to be released at any moment with a crash as the weight falls back to the ground.
How do we measure energy and work?
The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter.
How did the bullet gain energy?
The bullet gained this energy because work was done on it by a charge of gunpowder which lost some chemical potential energy in the process. A hot cup of coffee has a measurable amount of thermal energy which it acquired via work done by a microwave oven, which in turn took electrical energy from the electrical grid.
Is energy stored or measured?
Energy can be stored and measured in many forms. Although we often hear people talking about energy consumption, energy is never really destroyed. It is just transferred from one form to another, doing work in the process. Some forms of energy are less useful to us than others—for example, low level heat energy.
