Middle School Physical Science › Identify types of energy
Energy from the sun travels in waves to Earth where plants use a chemical process to convert it into food. This is an example of how:
radiation or solar energy is converted into chemical energy
radiation or solar energy is converted to hydroelectric energy
radiation or solar energy is converted to matter
radiation or solar energy is converted to wind energy
Radiation or solar energy is energy captured from the sun. Plants use this energy from the sun to undergo photosynthesis. Photosynthesis is the process of converting sunlight into good- which is a chemical process. Remember, a chemical process is a change. In this example, the sunlight is being changed into food.
What is happening to the energy from an electrical outlet when you plug in an oven and turn it on?
Electric energy from the outlet is transferred through wires which changes into heat energy from an oven
Electric energy from the outlet is transferred through wires which changes into solar energy from an oven
Magnetic energy from the outlet is transferred through wires which changes into heat energy from an oven
Magnetic energy from the outlet is transferred through wires which changes into solar energy from an oven
When something is plugged into an outlet, that means we are using electric energy.
When something is plugged into an outlet, it isn't capturing energy from the sun. Thus, "Electric energy from the outlet is transferred through wires which changes into solar energy from an oven" is not correct because we aren't using solar energy, or energy form the sun.
Magnetic energy is the potential energy of a magnetic field. And outlet and an oven do not use magnets to create energy.
The answer is "Electric energy from the outlet is transferred through wires which changes into heat energy from an oven."
Which of these is NOT an example of energy?
work
light
heat
motion
The answer is "work." Work is the displacement of an object by using force. Energy is required to do work but it is not work.
Matter is anything that has a mass and volume. Matter is made of small particles called atoms. Desks, chairs, people, plants, animals, rocks, water, the Earth, and anything else you can touch are made of atoms, and thus are considered matter. Some examples of things that are not matter are thoughts, ideas, heat, light, sound, and anything else that is not made of atoms.
Energy is the ability to do work. Energy exists as light, heat, and motion. It does not take up space or have mass. It is not made of atoms, but there is energy stored in the bonds between atoms and it requires energy to break them apart. We have classified many kinds of energy even though they are all technically light, heat, and motion.
Potential energy is stored energy. This can be paired with another description of energy. For example, "chemical potential" or "gravitational potential" energy are valid types of energy
Kinetic energy is motion energy. Also known as mechanical energy, this can also be a description of other types of energy. Sound, and temperature, are technically types of kinetic energy because they describe the motion of particles.
Nuclear energy is the energy stored within the nucleus of an atom.
Thermal energy is energy released or absorbed as heat.
Electric energy is energy from moving electrons.
Solar energy is energy from photons, or radiation from the sun.
Radiation is energy that moves in wave forms.
Energy stored in the nucleus of an atom is called:
nuclear energy
kinetic energy
sound energy
mechanical energy
Nuclear energy is the energy that holds together the nucleus of atoms. Atoms are the most simple blocks that make up matter. Every atom has in its center a very small nucleus. Normally, nuclear energy is hidden inside the atoms.
Kinetic energy is the energy that an object has because of its motion. This energy can be converted into other kinds, such as gravitational or electric potential energy, which is the energy that an object has because of its position in a gravitational or electric field.
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal. Sound energy is a form of mechanical energy.
Mechanical energy is power that an object gets from its position and motion.
Which of these lists contains ONLY examples of matter, and no examples of energy?
table, chair, wood, rocks, trees
wood, fire, trees, water, dirt
light, grass, wind, rocks, fire
water, gravity, stars, sun, leaves
The answer is "table, chair, wood, rocks trees." All of these are matter. The other examples contained: fire, wind, light, and gravity, which are not matter.

What kind of energy is stored in gasoline?
potential and chemical energy
potential and radioactive energy
kinetic and chemical energy
kinetic and nuclear energy
Energy is 'the ability to do work. Chemical energy is a type of potential energy that is energy due to the position of an object or objects. The potential energy is in the form of chemical bonds that are forces that hold the atoms together in a chemical.
The answer is "potential and chemical energy" because gasoline is combustible and stores chemical potential energy until it is ignited and that energy is released in an exothermic reaction.
Which of these is NOT a type of potential energy?
sound
gravitational
elastic
chemical
The answer is "sound." Potential energy is defined as stored energy, and energy can be stored in chemicals, by being up high, or by pulling on elastic. Sound is energy from the movement of particles and is therefore a type of kinetic energy.
There is a bowling ball rolling towards a collection of standing pins waiting to be knocked over. This is an example of what kind(s) of energy?
potential energy
kinetic energy
potential and kinetic energy
thermal energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Thus, he answer is both potential and kinetic energy because the ball is moving forward with kinetic energy and the pins are waiting to be knocked over with potential energy.
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. This question does not mention anything about temperature or heat, so this is not the correct answer.
The temperature of a substance is a type of:
kinetic energy
potential energy
both kinetic and potential energy
neither kinetic nor potential energy
Kinetic energy is the energy that an object has because of its motion. This energy can be converted into other kinds, such as gravitational or electric potential energy, which is the energy that an object has because of its position in a gravitational or electric field.
Potential energy is the type of energy associated with an object's potential to do work.
The answer is "kinetic energy" because temperature is a measure of the average kinetic energy of the particles in a substance
A solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels collect what type of energy?
solar energy
electric energy
nuclear energy
heat energy
Nuclear energy is the energy that holds together the nucleus of atoms. Atoms are the most simple blocks that make up matter. Every atom has in its center a very small nucleus. Normally, nuclear energy is hidden inside the atoms.
Electric energy is a form of energy resulting from the flow of electric charge.
Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
Solar energy is energy captured from the sun.
The answer is "solar energy" because the energy comes from the sun. They convert the solar energy to electric energy for further use.
