SUMMARY
The angular speed of the Earth in its orbit is defined as 1 radian per second, which corresponds to a full rotation of 2π radians completed in one day. To convert other angular speeds, such as 720, 50, and 1000, into radians per second, one must first calculate the total number of seconds in a day, which is 86,400 seconds. The formula to find the angular speed in radians per second is 2π divided by the number of seconds in a day, and this value should be multiplied by the given angular speeds to obtain the correct answers.
PREREQUISITES
