Match the terms to the correct descriptions.

this can be either kinetic or potential and has to do with the energy of position and motion of an object

this is radiant energy from the sun; it's the only kind of energy we can see with our eyes

this is energy that is transferred by the movement of electrons through a conductor: the electrons create a current.

this type of energy is often found in things like batteries or food

this type of energy travels through vibrations on waves

this is the energy found in the nucleus of an atom this is the term used when energy changes from one form to another

this type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band

this type of energy can be transferred in three different ways: 1) direction contact through collisions (also called conduction), 2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection), and 3) by waves traveling with or without a medium (also called radiation) this has to do with the speed of an object and how much mass it has; basically how the object is moving

1. mechanical energy

2. kinetic energy

3. potential energy

4. electrical energy

5. light energy

6. thermal energy

7. sound energy

8. chemical energy

9. nuclear energy

10.energy conversions

The type of energies or the words in this item are matched with the given descriptions. The lists below are as follow.

a. The word that best match this description is MECHANICAL energy. In most sources, mechanical energy is described to be that energy that is possessed by an object with respect to its motion and position.

b. The answer to this item is LIGHT energy. This type of energy can be created through different means (i.e. radiation, chemical, and mechanical). This is the energy emitted by hot objects such as the sun, lasers, and bulbs.

c. The type of energy that is transferred by the movement of the electrons through a conductor is ELECTRICAL energy. The movement of the electrons along the line is commonly called as the current. Moreover, this is also a type of kinetic energy because of the movement of the electrons. Thus, the faster the movement of the electron the higher is the energy.

d. The type of energy that is stored in batteries or food is CHEMICAL energy. This type of energy is that which is stored in the bonds of the different chemical compounds. This is also most commonly released when reaction between elements/compounds happen.

e. The energy that travels through vibrations and waves is SOUND energy. As given above, this is associated with the movement or vibrations of the matter. This is also a type of mechanical energy because of the waves produced through to the vibrations.

f. The type of energy that is found in the nucleus and atoms is the NUCLEAR energy.  Nuclear reactions most often released this type of energy simultaneous with the generation of heat.

g. The stored energy is called the POTENTIAL energy. The equation for this energy is mgh where h is the height, pertaining to the position of the object. Once the object is released, it will be converted to other forms of energy.

h. The answer to this item is THERMAL energy. This type of energy can be transferred in three different ways: (1) conduction, (2) convection, and (3) radiation.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
