Words : Definition
Energy: The ability to make something happen.
Potential energy: The ability to make something happen. Stored energy. The energy of the water in the lake behind a dam is potential energy. The water has energy because of its position. The more mass an object has, the more potential energy it has.
Kinetic energy: The energy of motion. Anything that is moving has kinetic energy. When you walk or run you have kinetic energy.
Mechanical energy: The energy in moving things. This type of energy can occur as potential or kinetic energy, or both. An example – when you wind the spring on a toy car, you are storing mechanical energy in the spring. When the toy is turned on, the spring unwinds and the mechanical energy of the spring is seen as the toy moves. Until the spring winds down completely, it has both potential and kinetic energy.
Electrical energy: the energy that flows through wires and powers the lights and appliances in your house.
Electromagnetic energy: visible light, also called radiant energy. Other examples are X-rays, radio waves and microwaves.
Heat energy: This energy is also called thermal energy, which is the energy of the moving particles that make up matter. The faster the particles move, the more heat energy they have. An example – rubbing your hands together, they become warm.
Chemical energy: The energy that holds particles of matter together. Examples: 1) the energy stored in the head of a match. 2) The energy stored in food 3) the energy in fuels such as wood and coal.
Nuclear Energy: The energy stored in the nucleus of an atom. Example –The heat and light from the sun are produced from this type of nuclear reaction.
Thermal pollution: Damage that occurs when waste heat enters the environment. When energy changes form, some of the energy is always changed into heat. Example: The water in lakes and rivers is used to remove waste heat from power plants. The waste heat makes the water warmer. If the water becomes too warm fish in the lakes will die.
Law of Conservation of Energy: This law says that energy cannot be made or destroyed, but only changed in form. Energy can also move from place to place, however, energy can never be lost.
In 1905 Albert Einstein showed that matter and energy are two forms of the same thing. Einstein explained that matter can be changed into energy, and energy can be changed into matter. The total amount of matter and energy in the universe does not change. Einstein explains this in the following equation of E = mc2
E is energy, m is matter , or mass and c is the speed of light. His equation showed that a small amount of matter could be changed into a huge amount of energy, and this is what happens in the Sun.

What’s in a name? From the Greek words hydro and genes, which together mean “water forming.”
Say what? Hydrogen is pronounced as HI-dreh-jen.
History and Uses:
According to Jlab.org scientists had been producing hydrogen for years before it was recognized as an element. Written records indicate that Robert Boyle produced hydrogen gas as early as 1671 while experimenting with iron and acids. Hydrogen was first recognized as a distinct element by Henry Cavendish in 1766.Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen.Hydrogen is the raw fuel that most stars ‘burn’ to produce energy. The sun’s supply of hydrogen is expected to last another 5 billion years.Hydrogen is a commercially important element. Large amounts of hydrogen are combined with nitrogen from the air to produce ammonia (NH3) through a process called the Haber process. Hydrogen is also added to fats and oils, such as peanut oil, through a process called hydrogenation. Liquid hydrogen is used in the study of superconductors and, when combined with liquid oxygen, makes an excellent rocket fuel.
Hydrogen combines with other elements to form numerous compounds. Some of the common ones are: water (H2O), ammonia (NH3), methane (CH4), table sugar (C12H22O11), hydrogen peroxide (H2O2) and hydrochloric acid (HCl).
