acceleration: A metamorphosis within the velocity or path of a few object.
aerodynamic: Having a form that reduces resistance from air flowing previous.
birds: Heat-blooded animals with wings that first confirmed up all through the time of the dinosaurs. Birds are jacketed in feathers and convey younger from the eggs they deposit in some type of nest. Maximum birds fly, however all the way through historical past there were 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 through an exquisite drive between the collaborating atoms. As soon as bonded, the atoms will paintings as a unit. To split the part atoms, power will have to be provided to the molecule as warmth or every other form of radiation.
centripetal drive: A drive that acts on an object because it strikes alongside a curved trail. This drive is directed into the middle of the curve or circle. (Centripetal manner “middle in the hunt for” in Latin.)
drag: A slowing drive exerted through air or different fluid surrounding a shifting object. It comes to friction. However not like easy friction, it will increase with an object’s velocity.
forage: To seek for one thing, particularly meals. It’s additionally a time period for the meals eaten through grazing animals, corresponding to farm animals and horses.
drive: Some outdoor affect that may alternate the movement of an object, cling gadgets shut to each other, or produce movement or pressure in a desk bound object.
elementary: One thing this is fundamental or serves as the basis for any other factor or concept.
gecko: A small to medium sized reptile present in heat to equatorial areas of the sector. Some 2,000 other species of this lizard exist, in quite a lot of colours. Those reptiles consume bugs, worms or even the occasional small chook. However they’re absolute best identified for with the ability to climb slick surfaces, owing to important constructions at the backside surfaces in their toes.
gravity: The drive that draws anything else 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 metamorphosis in its movement — or, for a resting object, to start shifting.
insect: One of those arthropod that as an grownup may have six segmented legs and 3 frame portions: a head, thorax and stomach. There are loads of hundreds of bugs, which come with bees, beetles, flies and moths.
carry: An upward drive on an object. It’ll happen when an object (corresponding to a balloon) is stuffed with a gasoline that weighs not up to air; it will possibly additionally outcome when a low-pressure space happens above an object (corresponding to an plane wing).
limb: (in body structure) An arm or leg.
style: A simulation of a real-world tournament (in most cases the use of a pc) that has been advanced to are expecting a number of most likely results. Or a person this is intended to show how one thing would paintings in or glance on others.
molecule: An electrically impartial crew of atoms that represents the smallest imaginable quantity of a chemical compound. Molecules may also be made from unmarried sorts of atoms or of various varieties. For instance, the oxygen within the air is made of 2 oxygen atoms (O2), however water is made of 2 hydrogen atoms and one oxygen atom (H2O).
navigate: To seek out one’s manner via a panorama the use of visible cues, sensory knowledge (like scents), magnetic knowledge (like an inner compass) or different tactics.
parallel: An adjective that describes two issues which might be aspect through aspect and feature the similar distance between their portions. Within the phrase “all,” the general two letters are parallel strains. Or two issues, occasions or processes that experience a lot in not unusual if in comparison aspect through aspect.
parkour: A time period, from the French, for a kind of gymnastics-like task the place other folks bounce via an atmosphere through leaping, jumping and scrambling up, round and between partitions and different stumbling blocks. Actions have a tendency to be very fast and fluid. Some might contain vaulting or flipping over railings, stairs or different constructions. Other folks may also climb up partitions or jump from one wall or fence to a few different construction.
physics: The medical find out about of the character and houses of topic and effort. Classical physics is an evidence of the character and houses of topic and effort that is dependent upon descriptions corresponding to Newton’s rules of movement. Quantum physics, a box of analysis that emerged later, is a extra correct manner of explaining the motions and behaviour of topic. A scientist who works in such spaces is referred to as a physicist.
predator: (adjective: predatory) A creature that preys on different animals for many or all of its meals.
resistance: (in physics) One thing that helps to keep a bodily subject matter (corresponding to a block of wooden, waft of water or air) from shifting freely, in most cases as it supplies friction to hinder its movement.
chance: The risk or mathematical chance that some unhealthy factor may occur. As an example, publicity to radiation poses a chance of most cancers. Or the danger — or peril — itself. (As an example: Amongst most cancers dangers that the folk confronted had been radiation and ingesting water tainted with arsenic.)
robotic: A system that may sense its setting, procedure knowledge and reply with particular movements. Some robots can act with none human enter, whilst others are guided through a human.
function style: Anyone whose ability, habits and/or character makes them an inspirational superb, the sort who conjures up others to style themselves after this particular person.
dash: To run at best velocity over a reasonably brief distance. In aggressive working, the 100-meter race is a dash. An individual who’s doing this type of working is named a sprinter.
tactic: An motion or course of action to perform a selected feat.
era: The appliance of medical wisdom for sensible functions, particularly in trade — or the gadgets, processes and programs that outcome from the ones 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 is the talent of one thing to withstand sliding, corresponding to a tire on a street or a sock-covered foot alongside a wooden ground. It isn’t the similar 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 speed varies irregularly as a substitute of keeping up a stable or calm waft.
van der Waals forces: One of those molecular appeal that works over very small distances.
vertical: A time period for the path of a line or aircraft that runs up and down, because the vertical publish for a streetlight does. It’s the other of horizontal, which might run parallel to the bottom.
vortex: (plural: vortices) A swirling whirlpool of a few liquid or gasoline. Tornadoes are vortices, and so are the tornado-like swirls inside of a tumbler of tea that’s been stirred with a spoon. Smoke rings are donut-shaped vortices.
vortices: (singular: vortex) Swirling whirlpools of a few liquid or gasoline. Tornadoes are vortices, and so are the tornado-like swirls inside of a tumbler of tea that’s been stirred with a spoon. Smoke rings are donut-shaped vortices.
