How do you find the angular velocity of the Earth?
When calculating the angular velocity of the Earth as it completes a full rotation on its own axis (a solar day), this equation is represented as: ωavg = 2πrad/1day (86400 seconds), which works out to a moderate angular velocity of 7.2921159 × 10-5 radians/second.
How can angular velocity be measured?
Angular velocity can be measured with a gyroscope, which consists of a spinning wheel mounted on a movable frame. When the wheel is spinning, it tends to retain its initial orientation in space, regardless of the central forces applied to it.
How do you find the angular velocity of the Earth around the sun?
We know the Earth goes round the Sun, all the way around is 2 radians (360 degrees). We also know that it takes a year (approx 365 days) which is therefore about 3.2×107 secs. Therefore = 2 / 3.2×107 = 2.0×10-7 rad/s. We have calculated the angular velocity.

What is the velocity of the earth around the sun?
30 kilometers per second
As schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour.
How do you find velocity at the equator?
Clearly, our velocity changes depending on whether we are at the equator or at the pole….[Answer]
- D = distance traveled = circumference [not area] of a circle.
- T = time.
- v = velocity = D/T.
- pi = 3.1415.
- R = radius of a circle (in this case the radius of the whole Earth since we live at the equator)
