Is there a difference between motion for an obect falling through hole at the center or falling through any two points??
 
Physics news on Phys.org
By any two points, I assume you mean a non-diameter chord?
 
yea. let's say a hole from uk to japan.
 
Hi. Both are oscillation around the deepest point of tunnel.
 
If you are at the middle of a chord, how does the force compare to when you are at the center of the earth?
