acceleration: A change within the pace or course of some object.
aerodynamic: Having a form that reduces resistance from air flowing previous.
birds: Warm-blooded animals with wings that first confirmed up in the course of the time of the dinosaurs. Birds are jacketed in feathers and produce younger from the eggs they deposit in some type of nest. Most birds fly, however all through historical past there have been the occasional species that don’t.
bond: (in chemistry) A semi-permanent attachment between atoms — or teams of atoms — in a molecule. It’s shaped by a lovely drive between the collaborating atoms. Once bonded, the atoms will work as a unit. To separate the part atoms, power have to be provided to the molecule as warmth or another sort of radiation.
centripetal drive: A drive that acts on an object because it strikes alongside a curved path. This drive is directed into the middle of the curve or circle. (Centripetal means “middle in search of” in Latin.)
drag: A slowing drive exerted by air or different fluid surrounding a shifting object. It entails friction. But not like easy friction, it will increase with an object’s pace.
forage: To seek for one thing, particularly meals. It’s additionally a time period for the meals eaten by grazing animals, akin to cattle and horses.
drive: Some outdoors affect that may change the movement of an object, maintain objects shut to 1 one other, or produce movement or stress in a stationary object.
basic: Something that’s primary or serves as the muse for one more factor or thought.
gecko: A small to medium sized reptile present in heat to equatorial areas of the world. Some 2,000 totally different species of this lizard exist, in a variety of colours. These reptiles eat bugs, worms and even the occasional small fowl. But they’re greatest recognized for having the ability to climb slick surfaces, owing to particular constructions on the underside surfaces of their toes.
gravity: The drive that draws something with mass, or bulk, towards some other factor with mass. The extra mass that one thing has, the larger its gravity.
inertia: The tendency of a shifting object to withstand a change in its movement — or, for a resting object, to start shifting.
insect: A sort of arthropod that as an grownup could have six segmented legs and three physique components: a head, thorax and stomach. There are a whole lot of hundreds of bugs, which embody bees, beetles, flies and moths.
raise: An upward drive on an object. It could happen when an object (akin to a balloon) is crammed with a gasoline that weighs lower than air; it will probably additionally consequence when a low-pressure space happens above an object (akin to an airplane wing).
limb: (in physiology) An arm or leg.
mannequin: A simulation of a real-world occasion (often utilizing a pc) that has been developed to foretell a number of doubtless outcomes. Or a person that’s meant to show how one thing would work in or look on others.
molecule: An electrically impartial group of atoms that represents the smallest attainable quantity of a chemical compound. Molecules might be product of single varieties of atoms or of various varieties. For instance, the oxygen within the air is product of two oxygen atoms (O2), however water is product of two hydrogen atoms and one oxygen atom (H2O).
navigate: To discover one’s approach by a panorama utilizing visible cues, sensory data (like scents), magnetic data (like an inside compass) or different strategies.
parallel: An adjective that describes two issues which can be facet by facet and have the identical distance between their components. In the phrase “all,” the ultimate two letters are parallel traces. Or two issues, occasions or processes which have a lot in frequent if in contrast facet by facet.
parkour: A time period, from the French, for a kind of gymnastics-like exercise the place folks soar by an atmosphere by leaping, leaping and scrambling up, round and between partitions and different obstacles. Movements are usually very speedy and fluid. Some could contain vaulting or flipping over railings, stairs or different constructions. People could even climb up partitions or leap from one wall or fence to another construction.
physics: The scientific examine of the character and properties of matter and power. Classical physics is a proof of the character and properties of matter and power that depends on descriptions akin to Newton’s legal guidelines of movement. Quantum physics, a discipline of examine that emerged later, is a extra correct approach of explaining the motions and conduct of matter. A scientist who works in such areas is called a physicist.
predator: (adjective: predatory) A creature that preys on different animals for many or all of its meals.
resistance: (in physics) Something that retains a bodily materials (akin to a block of wooden, move of water or air) from shifting freely, often as a result of it gives friction to impede its movement.
threat: The probability or mathematical probability that some unhealthy factor may occur. For occasion, publicity to radiation poses a threat of most cancers. Or the hazard — or peril — itself. (For occasion: Among most cancers dangers that the folks confronted have been radiation and consuming water tainted with arsenic.)
robotic: A machine that may sense its atmosphere, course of data and reply with particular actions. Some robots can act with none human enter, whereas others are guided by a human.
function mannequin: Someone whose ability, conduct and/or persona makes them an inspirational ultimate, the kind who evokes others to mannequin themselves after this individual.
dash: To run at prime pace over a reasonably brief distance. In aggressive operating, the 100-meter race is a dash. An individual who’s doing this sort of operating known as a sprinter.
tactic: An motion or plan of motion to perform a specific feat.
know-how: The utility of scientific information for sensible functions, particularly in business — or the units, processes and programs that consequence from these efforts.
traction: (in physics) The drive created as one thing pulls throughout a floor or the glue-like impact of friction created as one thing strikes alongside a floor. It’s the flexibility of one thing to withstand sliding, akin to a tire on a street or a sock-covered foot alongside a wooden flooring. It shouldn’t be the identical as friction however is said to friction.
turbulent: (n. turbulence) An adjective for the unpredictable fluctuation of a fluid (together with air) through which its velocity varies irregularly as a substitute of sustaining a regular or calm move.
van der Waals forces: A sort of molecular attraction that works over very small distances.
vertical: A time period for the course of a line or aircraft that runs up and down, because the vertical put up for a streetlight does. It’s the other of horizontal, which might run parallel to the bottom.
vortex: (plural: vortices) A swirling whirlpool of some liquid or gasoline. Tornadoes are vortices, and so are the tornado-like swirls inside a glass of tea that’s been stirred with a spoon. Smoke rings are donut-shaped vortices.
vortices: (singular: vortex) Swirling whirlpools of some liquid or gasoline. Tornadoes are vortices, and so are the tornado-like swirls inside a glass of tea that’s been stirred with a spoon. Smoke rings are donut-shaped vortices.
