How fast is a city on the earth's equator (such as Singapore) moving due to our planet's daily spin on its axis?
To calculate the speed of a city on the Earth's equator due to the planet's daily spin, you need to know the Earth's rotational period. The Earth completes one rotation on its axis in approximately 24 hours, which is equivalent to one day.
To find the speed of the city, you can use the formula:
speed = distance / time
In this case, the distance is the circumference of the Earth at the equator, and the time is the duration of one day.
1. First, determine the circumference of the Earth at the equator. The Earth's equatorial circumference is approximately 40,075 kilometers or 24,901 miles.
2. Next, convert the time into seconds. Since there are 24 hours in a day, and each hour has 60 minutes, and each minute has 60 seconds, you can calculate the time in seconds as:
24 hours * 60 minutes * 60 seconds = 86,400 seconds
3. Now, plug the values into the formula:
speed = 40,075 kilometers / 86,400 seconds
Calculating this equation will give you the speed of the city on the Earth's equator due to the planet's daily spin.
The result is approximately 0.463 kilometers per second or 1670 kilometers per hour.
Therefore, a city located on the Earth's equator, such as Singapore, is moving at a speed of about 0.463 kilometers per second due to the Earth's rotation.
