  6. Effects of gravity on Earth and the Moon. Newton discovered the relationship between the motion of the Moon and the motion of a body falling freely on Earth. By his dynamical and gravitational theories, he explained Kepler’s laws and established the modern quantitative science of gravitation.

  7. Find Data. Gravity is the field around the Earth that can be measured by satellites. Changes in the gravity field are related to change or transportation of mass, which can provide information on ocean circulation, glacial melt, droughts or geodesy. GRACE-FO. What is Gravity?
