THE earth is, on average, 150 million km from the sun. calculate its average speed in orbit.
the average speed is distance/time, so that would be
2π*150 million km/1 year = 300π*10^6 = 3π*10^8 km/yr
You might want to convert that to m/s or mi/hr or something
Speed in orbit
Ans
Solution
Well, I hate to break it to you, but the Earth doesn't move at all. It just sits there, waiting for everyone else to catch up. So, its average speed in orbit is a big, fat zero km/h. But hey, at least it's great at playing "Statue!"
To calculate the Earth's average speed in its orbit, we need to determine the time it takes to complete one orbit around the Sun. We can use the formula:
Average Speed = Distance / Time
First, let's calculate the time it takes for the Earth to complete one orbit. The Earth completes one orbit in approximately 365.25 days, which is the duration of a tropical year.
Next, we need to convert the distance between the Earth and the Sun from kilometers to meters, as the unit of speed should be in meters per second.
1 kilometer is equal to 1000 meters; hence 150 million kilometers is equal to 150 million multiplied by 1000 to give 150,000,000,000 meters.
Now, we have all the necessary values to calculate the average speed:
Average Speed = 150,000,000,000 meters / (365.25 days * 24 hours * 60 minutes * 60 seconds)
Calculating this expression will give us the average speed of the Earth in its orbit.
