Gravity and Newton's Laws of Motion, orbits History: Newton and Gravity 1670 . ..................  England o Isaac Newton Recognized that motion of a ball thrown  on Earth and motion of planets are  governed by  SAME  laws of physics.   Definitions: Mass - amount of matter in object weight - force of gravity on object volume - amount of space object occupies density - amount of mass in a volume acceleration - change in speed  or direction , includes  speeding up or slowing down See figure 2.5 for the definition of acceleration.  Here is a   link to the figure. Here is a more detailed discussion of acceleration (and   velocity and force). weight vs. mass gravity of moon is less than Earth => astronauts on moon have same mass, but weigh less Newton's Laws of Motion 1. An object remains at rest, or continues moving in a straight  line with constant speed, unless acted on by a force. This link has a more detailed description of the first law
