battery: A device that can convert chemical energy into electrical energy.
electricity: A flow of charge, usually from the movement of negatively charged particles, called electrons.
elevation: The height or altitude at which something exists.
engineer: A person who uses science and math to solve problems. As a verb, to engineer means to design a device, material or process that will solve some problem or unmet need.
excavate: (n. excavation) To dig something out of soil or rock (such as dinosaur bones); to remove the inner part of something to make a hole (cavity) within it.
force: Some outside influence that can change the motion of an object, hold objects close to one another, or produce motion or stress in a stationary object.
generator: A device used to convert mechanical energy into electrical energy.
gravity: The force that attracts anything with mass, or bulk, toward any other thing with mass. The more mass that something has, the greater its gravity.
grid: (in electricity) The interconnected system of electricity lines that transport electrical power over long distances. In North America, this grid connects electrical generating stations and local communities throughout most of the continent.
hydrogen: The lightest element in the universe. As a gas, it is colorless, odorless and highly flammable. It’s an integral part of many fuels, fats and chemicals that make up living tissues. It’s made of a single proton (which serves as its nucleus) orbited by a single electron.
kinetic energy: The energy held by an object due to its being in motion. The amount of this energy contained will depend on both the mass (usually weight) of the object and its speed.
mechanical engineer: Someone trained in a research field that uses physics to study motion and the properties of materials to design, build and/or test devices.
module: A set of standardized parts or independent units used to assemble a more complex structure. The module could be used to create a…
