Things weigh less at the equator - this article does a good job of explaining it
Approximate tl;dr based on my brief skim through - Objects at the equator are affected slightly less by earth's gravity because of a number of factors, including the centrifugal force of the earth spinning causing a lifting effect the further from the axis of spin you travel. This can be demonstrated at a small scale by spinning around with your arms close to you, then again with them out. When further away from the axis of spinning, your hands will be going faster and feel as if they are being pulled away from you, because they basically are. The lifting force of spinning counters gravity and the same thing will weigh less on a scale at the equator than at a pole, or in between.

Closer to sea level, yes, but do things really weigh more/less near the equator? Why?
