If the length of a pendulum is increased four times, its time period will become

accurate measurements of distance , mass and so on were made much before accurate measurement of time became possible why?

the swing of a pendulum gradually decreases with time . however , even then it is regarded as a reliable time keeping deviceWhen an object moves on a straight line with a constant speed it is called a uniform motion. Then , if an object ic moving on circular path with a constant speed is it also be known as uniform motion ? explain.
