Angular deceleration of the Earth

AI Thread Summary
The discussion focuses on calculating the average angular deceleration of the Earth between 1900 and 1977, noting that the Earth took 1.01 seconds longer to complete 365 rotations in 1977 compared to 1900. Participants emphasize the importance of understanding angular velocity and acceleration equations, particularly how to derive angular velocities for both years using the period of Earth's rotation. The total time interval of 77 years is converted into seconds for calculations, and the change in period is used to find the average angular deceleration. The conversation highlights the need for consistent units and the significance of solving equations symbolically before substituting numerical values.

I do not think you understand what "proportional to" means then...
What do you think I think it means then? And why are you so concerned?

if y is proportional to x, then y = kx for some constant k.
This is not the case here.

This seems like a good time to close this thread. The OP has been given a lot of help and there's not much more that we can do.

Thank you all for contributing here.
