| Term | Definition |
| Gravity | attractive field force between objects with mass |
| Universal Gravitation | Newton's Law that every object attracts every other object in the universe with a force determined by their masses and their distance |
| Newton's 3rd Law of Motion | forces between two objects are equal in magnitude but opposite in direction |
| Gravitational Constant | (G = 6.67x10^-11) relates the weak force of gravitational attraction between 2 bodies |
| Mass | total matter (stuff) within an object |
| Radius | distance from an object's center |
| Direct | relationship when one variable changes in the same way that another one does, such as gravity and mass |
| Inverse Squared | relationship when one variable changes in the opposite way of another, such as gravity and distance |
| Centripetal Force | unbalanced "center-seeking" net force acting on an object to keep it moving in a circular path |
| Centripetal Acceleration | "center-seeking" acceleration of an object moving along a circular path |
| Tangential Velocity | linear speed of any object moving along a circular path that is perpendicular to the centripetal force and acceleration |
| Path of Motion | either linear (straight) or circular |
| Weight | force pulling down on an object's mass due to gravity (a.k.a. gravitational force) |
| Normal Force | contact force that is perpendicular to the surface supporting an object |
| Tension Force | pulling force transmitted by a string, cable, chain, rope, etc. |
| Friction Force | resistance force parallel to a surface and acts opposite of the direction an object is moving |
| Rule of 1's | helps determine how much a variable changes when you change any other variable(s) by a certain factor |
| Period | time to travel in one complete circle |
| Magnitude | size or amount (number) |
