Calculating Radial Acceleration of Earth at Equator

In summary, the formula for calculating the radial acceleration of Earth at the equator is a = v^2 / r, where "a" is the radial acceleration, "v" is the tangential velocity, and "r" is the radius of the Earth at the equator. The tangential velocity at the equator is calculated by multiplying the angular velocity of Earth (2π radians / 24 hours) by the radius of the Earth at the equator. The value of the radial acceleration of Earth at the equator is approximately 0.034 m/s^2, which is relatively low compared to other planets. This is due to Earth's large radius and slow rotation.

I need to calculate the radial acceleration of Earth @ the equator

a=v^2/r
a= [1041m/s)^2]/6378m
a= 169.9 m/s^2

is this correct?

I think the radius of the Earth is a tad larger than 6.4 km.
How did you get the v? The distance traveled in a day is the circumference of the equator.

Yes, your calculation is correct. The radial acceleration of Earth at the equator is approximately 169.9 m/s^2. This value represents the acceleration of an object moving at a constant speed around the Earth's equator due to the Earth's rotation. It is important to note that this value may vary slightly depending on the exact location on the equator and other factors such as the Earth's shape and rotation speed. However, your calculation provides a good estimate for the radial acceleration at the equator.
 

1. What is the formula for calculating the radial acceleration of Earth at the equator?

The formula for calculating the radial acceleration of Earth at the equator is a = v^2 / r, where "a" is the radial acceleration, "v" is the tangential velocity, and "r" is the radius of the Earth at the equator.

2. How is the tangential velocity at the equator calculated?

The tangential velocity at the equator is calculated by multiplying the angular velocity of Earth (2π radians / 24 hours) by the radius of the Earth at the equator.

3. What is the value of the radial acceleration of Earth at the equator?

The value of the radial acceleration of Earth at the equator is approximately 0.034 m/s^2.

4. How does the radial acceleration of Earth at the equator compare to other planets?

The radial acceleration of Earth at the equator is relatively low compared to other planets due to its large radius and slow rotation. For example, Jupiter has a much larger radial acceleration due to its faster rotation and smaller radius.

5. How does the rotation of Earth affect the calculation of its radial acceleration at the equator?

The rotation of Earth affects the calculation of its radial acceleration at the equator because it contributes to the tangential velocity, which is a crucial component of the formula for radial acceleration. The faster the rotation, the higher the tangential velocity and therefore the higher the radial acceleration.
