Orbital Speed and Distance Formula

Oct 13, 2025 by talynt.org 10 views

In this problem, we are presented with a satellite that completes one revolution around a planet in almost exactly one hour. The satellite has traveled a significant distance of $$2.0 \times 10^7$$ meters and is only 10 meters away from its starting point at the end of one hour. Our goal is to determine the correct answer to this problem.

The Key to the Problem: Orbital Speed and Distance

To solve this problem, we need to understand the relationship between the satellite's orbital speed, distance traveled, and the time it takes to complete one revolution. The key to this problem lies in the concept of orbital speed, which is the speed at which an object orbits a celestial body.

Orbital Speed and Distance Formula

The formula for orbital speed is given by:

v = \frac{2\pi r}{T}

where:

$v$$ is the orbital speed$
$r$$ is the radius of the orbit$
$T$$ is the time period of the orbit$

We are given that the satellite has traveled $$2.0 \times 10^7$$ meters in one hour, which is equivalent to 3600 seconds. We can use this information to calculate the orbital speed of the satellite.

Calculating Orbital Speed

Using the formula for orbital speed, we can calculate the orbital speed of the satellite as follows:

v = \frac{2\pi r}{T}

v = \frac{2\pi \times 2.0 \times 10^7}{3600}

v = 1.1 \times 10^4 \, \text{m/s}

Understanding the Significance of Orbital Speed

The orbital speed of the satellite is a critical factor in determining its motion around the planet. The higher the orbital speed, the faster the satellite will complete one revolution around the planet.

The Final Answer: A Satellite's Orbital Motion

Based on the calculations above, we can conclude that the satellite has an orbital speed of $$1.1 \times 10^4 , \text{m/s}$$. This value represents the speed at which the satellite orbits the planet.

Conclusion

In conclusion, the problem presented in this article requires a deep understanding of orbital speed and distance. By using the formula for orbital speed, we can calculate the orbital speed of the satellite and determine the correct answer to the problem.

Frequently Asked Questions: A Satellite's Orbital Motion ===========================================================

In this article, we will answer some of the most frequently asked questions related to a satellite's orbital motion.

Q: What is orbital speed?

A: Orbital speed is the speed at which an object orbits a celestial body, such as a planet or a moon. It is a critical factor in determining the motion of the object around the celestial body.

Q: How is orbital speed calculated?

A: Orbital speed can be calculated using the formula:

v = \frac{2\pi r}{T}

where:

$v$$ is the orbital speed$
$r$$ is the radius of the orbit$
$T$$ is the time period of the orbit$

Q: What is the significance of orbital speed?

A: The orbital speed of a satellite is a critical factor in determining its motion around the planet. The higher the orbital speed, the faster the satellite will complete one revolution around the planet.

Q: How does the radius of the orbit affect the orbital speed?

A: The radius of the orbit has a direct impact on the orbital speed. As the radius of the orbit increases, the orbital speed also increases.

Q: What is the relationship between orbital speed and time period?

A: The orbital speed and time period are inversely proportional. As the time period increases, the orbital speed decreases, and vice versa.

Q: Can you provide an example of how to calculate orbital speed?

A: Let's consider an example where a satellite orbits a planet with a radius of $$2.0 \times 10^7$$ meters and a time period of 3600 seconds. Using the formula for orbital speed, we can calculate the orbital speed as follows:

v = \frac{2\pi r}{T}

v = \frac{2\pi \times 2.0 \times 10^7}{3600}

v = 1.1 \times 10^4 \, \text{m/s}

Q: What is the difference between orbital speed and linear speed?

A: Orbital speed refers to the speed at which an object orbits a celestial body, while linear speed refers to the speed at which an object moves in a straight line. The two speeds are different and should not be confused with each other.

Q: Can you provide some real-world examples of orbital speed?

A: Yes, here are some real-world examples of orbital speed:

Satellite Orbits: Satellites in orbit around the Earth have orbital speeds ranging from $$7.5 \times 10^3$$ m/s to $$8.0 \times 10^3$$ m/s.
