Would one weigh more on the equator or on the North Pole?

AI Thread Summary
Weight differs between the equator and the North Pole due to variations in gravitational acceleration, which is approximately 9.78 m/s² at the equator and 9.83 m/s² at the poles. The Earth's shape, being an oblate spheroid, means that polar points are closer to the core, contributing to increased weight at the North Pole. Additionally, the Earth's rotation creates a centrifugal force that reduces weight at the equator compared to the poles. Thus, one would weigh more at the North Pole than at the equator. Understanding these factors clarifies the reasoning behind weight differences based on geographic location.

Hello, just wondering if you could apply Fg=mg to this. So the gravitational forces on the equator versus on the North Pole would differ and therefore, you would weigh more on the North Pole. According to what I found, the the gravitational acceleration is 9.78 m/s2 at the equator and 9.83 m/s2 at the poles. Does this reasoning make sense?

Sure;

Earth is not a perfect sphere as we all know, Polar points are closer to the core of the Earth than Equator.So you weigh more in the North pole then equator.

And of course you can use F=m.g to see that, just insert the "g" for poles and equator,
 
Thanks, good to know that I make sense.

Not only that, but the Earth is rotating as well, so there is a centrifugal force pulling you up that decreases with higher latitudes.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
