Dragoon said:The Earth has an orbit of radius 148 million km around the sun. What is the speed of the Earth on this orbit?
dont know how to do it i have used a couple of different formulas and haven't gotten it right can anyone help?
Period T = 365 days = ... seconds.NateTG said:How long does the Earth take to make an orbit around the sun?
What distance does the Earth travel in an orbit?
(Since the problem tells you that the orbit has a radius you can probably safely approximate the orbit with a circle of the appropriate radius.)
Then you can find speed using [tex]s=\frac{d}{t}[/tex] although you might want to do some unit conversion.
Earth's orbital speed around the sun is approximately 67,000 miles per hour, or 107,000 kilometers per hour.
Earth's orbital speed is affected by several factors, including its distance from the sun, the gravitational pull of other planets, and the tilt of its axis. These factors can cause variations in Earth's orbital speed throughout the year.
Earth's orbital speed is calculated using the formula v = 2πr/T, where v is the orbital speed, π is a mathematical constant, r is the distance between Earth and the sun, and T is the time it takes for Earth to complete one orbit.
Yes, Earth's orbital speed can change over time due to various factors, such as gravitational interactions with other planets, changes in Earth's orbit, and changes in the sun's gravitational pull.
Earth's orbital speed is relatively fast compared to other planets in our solar system. For example, Mercury's orbital speed is about 112,000 miles per hour, while Neptune's orbital speed is only 12,000 miles per hour.
