Matter in Motion: Earth''s Changing Gravity
This map, created using data from the Gravity Recovery and Climate Experiment (GRACE) mission, reveals variations in the Earth''s gravity field. Dark blue areas show areas with lower than normal
Sir Isaac Newton
As the years progressed, Newton completed his work on universal, diffraction of light, centrifugal force, centripetal force, inverse-square law, bodies in motion and the variations in tides due to gravity. His

Matter in Motion: Earth''s Changing Gravity | NASA Earthdata
A new satellite mission sheds light on Earth''s gravity field and provides clues about changing sea levels.
StarChild: Stars
Gravity causes the last of the star''s matter to collapse inward and compact. This is the white dwarf stage which is extremely dense. White dwarfs shine with a white hot light but once all of their energy is
What is gravity?
Newton''s "law" of gravity is a mathematical description of the way bodies are observed to attract one another, based on many scientific experiments and observations. The gravitational equation says
StarChild: Did you know... (The Sun)
The Sun''s gravitational pull is so strong that a 100 pound person would weigh 28 times that, or 2800 pounds, on the Sun.
Teachers'' Center Activity: Gravity Effects on Planet Motion
1. Introduction: Review the definition of gravity Drop a ball and explain why it falls downward Explain that the strength of a gravitational pull is determined by the masses of the objects involved and the
Gravity/Gravitational Field
Gravity is one of the most fundamental forces of not just our planet, but the universe as a whole. Specifically, it''s the “pull” any object with mass exerts on every other object with mass. The
