| Air resistance | Fritional force air exerts on a moving object acts oppsite in direction to the objects in motion. |
| Artificial satellite | human made device that orbits earth used for commintication, weather monitoring, military, & scientific purposes. |
| Centripetal acceleration | Acceleration toward the center of a circle by an object moving along a circular path. |
| Centripetal force | Force that causes an object moving along a circular path to move toward the center of the path. |
| Law of conservation of momentum | Law stating that the toatl momentum of a group of objects is conserved unless a net force acts on the objects. |
| Momentum | A property of any moving object, it is the product of its mass and velocity (p=mv) |
| Newtons 2nd law | Shows acceleration of an object in the direction of the net force applied to it |
| Newtons 3rd law | Shows action reaction pairs for every ation force their is an reaction |
| Projectile | Object shot or thrown through the air, have both horizontal and vertical velocities |
| Terminal velocity | The greatest volisity reached by a falling object. Achieved when force of gravity is balanced by air resistance. |
