3.1 review

Precision measurements of the acceleration  due to gravity show that the acceleration is slightly different in different locations on Earth. Explain why the force of gravity is not exatly the same everywhere on Earth's surface.

Because of the air, gravity effect may change. If you are in Mount Everest, you'll have less gravity force. If you are in the deep ocean there will be more gravity for the air and water's pressure.
