| Friction | The force that acts to resist the relative motion of objects or materials that are in contact. |
| Inertia | The property of anay body to resist changes in its state of motion. Mass is the measure of inertia. |
| Newton's first Law (Law of Inertia) | everybody continues in its state of rest, or of motion in a straight line at constant speed, unless acted upon by a non-zero force. |
| Law of Inertia (Newtons first Law) | everybody continues in its state of rest, or of motion in a straight line at constant speed, unless acted upon by a non-zero force. |
| Kilograms | the fundamental SI unit of mass. One kilogram (kg) is the amount of mass in one liter of water at 4 degrees C |
| mass | A measure of an objects inertia; also a measure of the amount of matter in an object. Depends only on the amount of and kind of particles that compose an object-not on its location |
| Newton | SI unit of force. One newton (N) is the force applied to a one-kilogram mass that will produce an acceleration of one meter per second per second m/s/s |
