into the vehicle. · Roof rack: a set of bars secured to the roof of a motor car.[1] It is used to carry bulky items such as luggage, bicycles, canoes, kayaks, skis, or various carriers and containers. · Spoiler: an automotive aerodynamic device whose intended design function is to 'spoil' unfavourable air movement across a body of a vehicle in motion, usually described as drag. Spoilers on the front of a vehicle are often called air dams, because in addition to directing air flow they also reduce the amount of air flowing underneath the vehicle which generally reduces aerodynamic lift and drag. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic
Relatiivsusteooria Eva-Lotta Metsla, Gertrud Sildnik, Kati Eliisabet Peterson, Getter Jalakas ja Mia Martina Peil Kõik on suhteline Ei ruum ega aeg, ega isegi keha mass ei ole kindlad, absoluutsed suurused, vaid on “relatiivsed”. Valguse kiirus Umbes 300 000 km/s Jääb vaakumis alati samaks Seda ei saa ületada Valgus äitub teisiti, kui teised kehad Kehad käituvad väga kummaliselt, kui neid panna liikuma valguse kiirusel Albert Michelson Tõestas, et valguse kiirus ei sõltu Maa liikumisest Ei ole olemas mingit absoluutset ruumi Ligikaudselt valguse kiirusel liikudes aeg aeglustub Relatiivsusteooriat on suudetud ka Maa-pealsete katsetega tõestada Massi suurenemine Mass on keha inertsuse mõõt Kui erineva massiga kehi mõjutada sama suure jõuga, kasvab suurema massiga keha kiirus aeglasemalt Mass sõltub liikumiskiirusest Mass kasvab valguse kiir...
