在解决天体的运动问题时,学生很容易把地球的自转周期跟围绕地球表面运动的卫星或飞行物的周期混为一谈,从而导致一些错误的结果.例1 某航天飞机在地球赤道上空飞行,轨道半径为 r,飞行方向与地球的自转方向相同,设地球的自转角速度为ω_0,地球半径为 In solving the problem of movement of celestial bodies, students can easily confuse the Earth’s rotation cycle with the cycle of satellites or flying objects orbiting the Earth’s surface, resulting in some erroneous results. Example 1 A space shuttle flies above the Earth’s equator, orbiting radius For r, the direction of flight is the same as the direction of rotation of the earth. Let the earth’s angular velocity be ω_0 and the radius of the earth be
