Energy and Work
... Work is not energy itself, but rather a transfer of energy. A force does work on an object if it causes the object to move. Work is always done on an object and results in a change in the object. The work done is equal to the change in energy. ...

... and acts along the line joining the centers of mass of the two masses. The forces on the two masses are equal in size but opposite in direction, obeying Newton's third law. Viewed as an exchange force, the massless exchange particle is called the graviton. The gravity force has the same form as Coul ...

... Think back to the astronauts on the moon. The moon’s mass is much smaller than Earth’s mass. Therefore, objects near the moon experience a smaller gravitational force than objects near Earth. The astronauts could jump very high on the moon because the gravitational force on them was small. Another w ...
