One famous example of this situation was seen with the Mars Climate Orbiter.

Unit conversions may not seem very interesting, but not doing them can be costly. Average speed and other motion concepts are covered in later chapters.) In equation form, (Take this definition as a given for now. Average speed is distance traveled divided by time of travel. We also want to convert minutes to seconds, so we use the conversion of 60 s in 1 min. In this case, we want to convert miles to meters, so we need to know the fact that there are 1609 m in 1 mi. The correct conversion factors are those that cancel the unwanted units and leave the desired units in their place. ( Note: Average speed is distance traveled divided by time of travel.) Strategyįirst we calculate the average speed using the given units, then we can get the average speed into the desired units by picking the correct conversion factors and multiplying by them. Calculate the average speed in meters per second (m/s). The distance from the university to home is 10 mi and it usually takes 20 min to drive this distance. We write the units we have and then multiply them by the conversion factor so the units cancel out, as shown:Įxample Converting Nonmetric Units to Metric In this case, we know that there are 1000 m in 1 km. Refer to Appendix B for a more complete list of conversion factors. in 1 ft, 1609 m in 1 mi, 100 cm in 1 m, 60 s in 1 min, and so on.

A conversion factor is a ratio that expresses how many of one unit are equal to another unit. Next, we need to determine a conversion factor relating meters to kilometers. In this case, we have units in meters and we want to convert to kilometers. The first thing to do is to list the units you have and the units to which you want to convert. Suppose we want to convert 80 m to kilometers.
#CALCULATE THE AVERAGE SPEED, IN KILOMETERS PER SECOND, OF THE EARTH IN ITS ORBIT HOW TO#
Let’s consider a simple example of how to convert units. In this case, you may need to convert units of feet or meters to miles. Or perhaps you are reading walking directions from one location to another and you are interested in how many miles you will be walking. For example, if you are reading a European cookbook, some quantities may be expressed in units of liters and you need to convert them to cups. It is often necessary to convert from one unit to another.

Wilkins will a little bit with this, and she got into a one right there. And if you want a motorway that to get rid of meters, your 1000 meters secret one kilometer, some years will cancel Alex, tend to the three. So if we divide this by we're here All right, it up like this, I guess. We know that there, um into the three meters is equal to one kilometer. All right, meters per second years for second, or we're gonna lose those kilometres for a second. Now, this is essentially what we want for our second answer, right meters per second. Did you put one point Marine buying trends 10 to the fourth meters per second. All right, So, um, if you put that into your calculator, you're gonna get that. So that's exactly the direction we want to be going here. All right, So you want, um, find meters per second. All right, if you do all that math we're gonna need getting into that books, Uh, something like this 1536 times 10 to be seven seconds. So 60 times sixties, 3600 seconds in one hour. 60 minutes, which is equal to 60 seconds. What, these? I'm gonna learn howto English. So for you and 65 days we're gonna changed these units. And we know that the earth job was, uh, around the sun in a boat threw him from 65 days. All right, so that is our distance right there. Recall that the circumference of a circle is two pi r Did you do to pi times 10 to the 11th? That is equal to about 6.28 three. So here we are, coming around the orbiting the sun, and we're at an average distance right here, which I will call our for radius. Um, I wish I had a yellow marker, but I don't. We're gonna draw part of the solar system here. So first, to solve this problem, we needed to know the average distance from the earth to the sun. So if this problem, we want to find out how fast In kilometers proud are kilometers per second and in meters per second is thier earth orbiting the sun.
