我们知道钟表面一周被等分成12个大格,60个小格,时针每小时转1大格,即5小格,分针1分钟转1小格,秒针1秒钟转1小格.钟表面上时针、分针、秒针各自绕着钟面的中心(圆心)做(匀速)圆周运动,时针的角速度为π/6小时,分针角速度为2π/小时,秒针的角速度为120π/小时,由于三针的速度不同,从0时起到某一时刻,根据三个针的位置我们可以读出时
We know that the surface of the clock is equally divided into 12 large lattices and 60 small lattices one week, and the hour hand rotates 1 large lattices, that is, 5 small lattices, the minute hand changes 1 small cell in 1 minute, and the second hand turns 1 small cell in 1 second. The hour hand, minute hand and second hand each make (uniform) circular motion around the center (center) of the clock face, the angular velocity of the hour hand is π / 6 hours, the angular speed of the minute hand is 2π / hour and the angular speed of the second hand is 120π / The speed is different from 0 o’clock until a certain moment, according to the location of the three needles we can read
