accelerate: To undergo a change in speed (velocity).
atmosphere: A layer of gas surrounding the Earth, another planet, or the Moon.
atom: The basic unit of chemical elements. Atoms consist of a dense nucleus containing positively charged protons and uncharged neutrons, orbited by a cloud of negatively charged electrons.
atom: Relating to atoms, which are the smallest units that form chemical elements.
chemicals: Substances formed when two or more atoms combine in a specific proportion and structure. For example, water is a chemical produced when two hydrogen atoms combine with one oxygen atom, with a chemical formula of H2O.
continuous: Uninterrupted or unceasing. In mathematics, a known and unchanging number, such as π (pi).
cosmos: Referring to the universe and everything within it.
size: A measurable descriptive characteristic of something, such as length, width, or time.
engine: A machine that converts energy into useful mechanical motion, also known as a motor. In computer science, a program that performs a specific range of functions.
engineer: A person who uses science and mathematics to solve problems, or the act of designing a device, material, or process to address a need.
exoplanet: Abbreviation for extrasolar planet, referring to a planet orbiting a star outside the solar system.
fiction: Invented ideas or stories, distinct from actual events.
force: External influences that can alter the motion of objects, move objects closer together, or induce motion or stress in stationary objects.
friction: Resistance encountered by one surface or object as it moves over or through another substance, leading to heating and possible damage.
fuel: A substance that releases energy during a controlled chemical or nuclear reaction, such as fossil fuels like coal, natural gas, and oil.
fusion: The process of combining two things to form a new entity, or in physics, the forcing together of atomic nuclei to release energy.
gravity: A force that attracts objects with mass or volume to one another, with greater mass resulting in stronger gravitational force.
interstellar: Referring to the space between stars.
ion: An atom or molecule that acquires a charge due to the loss or gain of electrons.
lever: A stiff bar used to move heavy loads when pressure is applied, or as a device component to act as a switch.
light year: The distance light travels in one year, approximately 9.46 trillion kilometers.
Mars: The fourth planet from the Sun, with seasons and humidity but a diameter only about half of Earth’s.
mass: A measure indicating how much an object resists acceleration and deceleration, based on its material amount.
momentum: A measure of an object’s motion, obtained by multiplying its mass and velocity.
nuclear power: Energy obtained from processes involving the splitting or fusion of atomic nuclei, used in nuclear power plants to generate electricity.
oxidizing agent: A substance that produces oxygen and causes the combustion of another substance.
particle: A trace amount of something.
photon: The smallest possible amount of light or electromagnetic radiation.
physics: The scientific study of the nature and properties of matter and energy, explaining matter and energy based on different descriptions like Newton’s laws of motion.
planet: A large celestial body that orbits a star without producing visible light.
plastic: Materials that are deformable or synthetic made from polymers, lightweight, and resistant to deterioration.
polymer: A substance made from long chains of repeating groups of atoms, including materials like nylon and plastics.
pressure: Force applied uniformly over a surface, measured as force per unit area.
promotion: Using force to move something forward, such as a jet engine used for propulsion in flying an airplane.
red planet: Nickname for Mars.
reflective: Referring to objects that strongly reflect light, producing glare when sunlight reflects off them.
rocket: Something propelled into the air or space, ascending due to exhaust gases released during fuel combustion.
science fiction: Literary or cinematic stories set in a fantasy background based on speculation about future science and engineering developments.
sea: Salty ocean or an area within the ocean.
society: An integrated group of humans or animals cooperating and supporting each other for the greater good.
solar: Relating to the sun or its emitted radiation.
solar system: The major planets and moons orbiting the sun, along with smaller celestial bodies like dwarf planets, asteroids, meteoroids, and comets.
solar wind: A stream of charged particles emitted from the surface of a star like the Sun, with the potential to penetrate the solar system.
speed of light: A constant speed in physics, around 1.08 billion kilometers per hour.
star: Celestial bodies that make up galaxies, formed when gas clouds are compressed by gravity and emit light when hot enough.
system: A network of parts working together to perform a function, whether biological systems in a body or infrastructure systems like railways.
technology: The application of scientific knowledge for practical purposes, leading to devices, processes, and systems.
thrust: A force moving an object forward.
thruster: An engine that propels by ejecting a stream of fluid, gas, or particles.
unique: Something distinct and unlike others, the only one of its kind.
universe: Everything beyond time and space, expanding since the Big Bang event about 13.8 billion years ago.
Venus: The second outermost planet from the Sun, with a rocky core and extreme surface conditions.
