The gravitational equation says that the force of gravity is proportional to the product of the two masses (m 1 and m 2), and inversely proportional to the square of the distance (r) between their centers of mass These uneven mass distributions influence satellite trajectories since areas of higher mass exert more force than areas of lower mass (from newton’s second law of motion A new satellite mission sheds light on earth's gravity field and provides clues about changing sea levels.

Gravity is the field around physical bodies, such as planets, that draws objects toward its center
Earth's gravitational field can be measured by orbiting satellites that can detect changes to it
These variations are related to change or transportation of mass, which can provide information on ocean circulation, glacial melt, droughts, or geodesy Nasa's gravity recovery and climate. 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 distance between the objects hold up a scale model of earth and a scale model of the sun Inquire as to which object would exert a stronger pull
A glacier is a large accumulation of many years of snow, transformed into ice This solid crystalline material deforms (changes) and moves Glaciers, also known as “rivers of ice,” actually flow Gravity is the cause of glacier motion
The ice slowly flows and deforms (changes) in response to gravity
A glacier molds itself to the land and also molds the land as it creeps down the valley. 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 gone, they die
The star has now reached the black dwarf phase. Gravitational pull see gravity gravity the force of attraction between two objects which is influenced by the mass of the two objects and the distance between the two objects Gyroscope a heavy wheel or disk mounted so that its axis can turn freely in one or more directions A spinning gyroscope tends to resist change in the direction of its axis.
Gravity waves are a real challenge because they are largely invisible to climate and weather models
The crux of the problem is the way satellites see them Gravity is not constant across earth, and the amount of force exerted by gravity changes with changes in mass
