Introduction
Gravitational force is a force that is evident in our everyday lives and plays a crucial role in many processes on Earth. For instance, the ocean tides are caused by the gravitational attraction of both the Moon and Sun on the Earth’s oceans.


Interesting Fact
This app is produce real numbers to coincident with the real world data.
