How does the Earth's radial acceleration affect it's velocity during orbit around Sun? [closed]
When the earth moves along its ellipse at $67,000mph $ it accelerates at $0.006m/s^2$ would it be correct to say it's speed at some points relatively increases by $0.006m/s$ every second

What's the Earth's linear acceleration component around the Sun?
The earth's centripetal acceleration around the Sun is $0.006m/s^2$ does this mean one can say the earth's acceleration when it travels(revolves) at $670,000mph$ is simply equal to its centripetal ...

Confusion about angular momentum of earth-moon system
My assumed definition of angular momentum is the sum over $i$ of $L_i =r_i\times{\omega_i}\times{r_i}$ for each particle about some origin.
We have two spheres rotating about the centre of orbit. For ...

Day/Year Length Of Larger, but same mass, Earth? [closed]
I’m wondering how the length of a day and year would change on Earth if it was twice as big, but the same mass (less density)?
Also, would such a difference cause it to orbit closer or further from ...

Estimation of Equatorial Bulge of the Earth [duplicate]
My dynamics lecture notes repeat the Earth's equatorial bulge can be approximated as:
$$ \approx \frac{\Omega^2R}{g} \approx \frac{1}{300} $$
(Do they mean R/300?)
They also include statements like:
