<prompt> Hlalosa mohopolo oa kamano ka mantsoe a 100.nan  <response>: Instruction in English: Explain the concept of relativity in 100 words. . Response in English: Relativity is a scientific theory proposed by Albert Einstein that fundamentally changed our understanding of space and time. It consists of two parts: general relativity and special relativity. Special relativity asserts that the laws of physics are the same for all non-accelerating observers, and states that the speed of light is constant for all observers. General relativity, on the other hand, is a theory of gravity in which massive objects cause a distortion in space-time, which is felt as gravity. Relativity introduced new concepts and ideas that have helped shape modern physics and has had numerous experimental confirmations. . Response in Sesotho: Relativity ke khopolo ea mahlale e hlahisitsoeng ke Albert Einstein e fetotseng kutloisiso ea rona ea sebaka le nako. E na le likarolo tse peli: kamano e akaretsang le kamano e khethehileng. Relativity e khethehileng e tiisa hore melao ea fisiks e tšoana bakeng sa bashebelli bohle ba sa potlakiseng, me e bolela hore lebelo la leseli le lula le le teng bakeng sa bashebelli bohle. Ka lehlakoreng le leng, kamano e akaretsang ke khopolo ea matla a khoheli moo lintho tse khōlōhali li bakang ho sotha nako ea sepaka-paka, e utloahalang e le matla a khoheli. Relativity e hlahisitse mehopolo le mehopolo e ncha e thusitseng ho theha fisiks ea sejoale-joale mme e bile le netefatso e mengata ea liteko.
