The gravitational acceleration g at Earth's surface actually depends slightly on latitude: this means that a ball that is dropped at the equator will accelerate slightly differently than one that is dropped in Ottawa in Canada. At Angel Falls in Venezuela(latitude 5°58'03" N) the acceleration is about 9.78 m/s2, while at Mount Ossa IN Tasmania (latitude 4152'12" S) the acceleration is about 9.80 m/s2.The difference may seem small, but which place would offer a higher power input Pin for a hydroelectric dam (if the water flow rate and water level drop are the same)? Mount Ossa, Tasmania. The power input would be equal Angel Falls,Venezuela.
