| 9580873721 | Force | A push or a pull | 0 | |
| 9580873722 | Net Force | The resultant of all forces acting on an object. Causes the object to changes its state of motion. | 1 | |
| 9580873723 | Weight | The force of gravity pulling on a given mass. Fw = m∙g | 2 | |
| 9580873724 | Force of Friction | A resistive force that acts on an object opposite the direction of motion. | 3 | |
| 9580873725 | Kinetic Friction | The resistive force that opposes the motion of a moving object. | 4 | |
| 9580873726 | Static Friction | The resistive force that keeps an object at rest when a force is applied to it. ALWAYS equal to the applied force. | 5 | |
| 9580873727 | Normal Force | The supportive force from a surface of contact. It is ALWAYS EXACTLY perpendicular to the surface. | 6 | |
| 9580873728 | Coefficient of Friction | A ratio that describes the relative stickiness between two surfaces in direct contact. Maximum static is ALWAYS larger than kinetic. | 7 | |
| 9580873729 | Newton's First Law | An object will maintain constant linear velocity until acted on by an outside net force. | 8 | |
| 9580873730 | Newton's Second Law | A net force applied to an object will cause the object to accelerate. Acceleration is directly related to the magnitude of the net force. Acceleration is in the same direction as the net force. Acceleration is inversely related to the mass of the object. | 9 | |
| 9580873731 | Newton's Third law | For every force there is an equal and opposite force. The forces are exactly equal in magnitude and directly opposite in direction. The forces occur simultaneously on SEPARATE objects. | 10 | |
| 9580873732 | Free-Body Diagram | A sketch of the forces being applied to a given object. Used to analyze all situations. |  | 11 |
| 9580873733 | Tension | Pulling force that is exerted by a stretched, taut rope, cable, or string. Must be determined through use of a FBD. | 12 | |
| 9580873734 | Inclined Plane | A slanted surface along which a force moves an object to a different elevation. Also called a ramp. Shift the X- and Y-planes to work with objects on inclined planes. |  | 13 |
| 9580873735 | Resultant | The sum (or combination) of all vectors. Determined using the Head-to-Tail Method. | 14 | |
| 9580873736 | Inertia | An object's resistance to changes in its state of motion. Comes from the matter/mass the object is made of. | 15 | |
| 9580873737 | Mass | Measure of an object's inertia. Measured in kilograms (kg). Total amount of matter (atoms, particles, etc.) that are present. | 16 | |
| 9580873738 | Equilibrium | A state that occurs when the net force on an object or system is zero. | 17 | |
| 9580873739 | Static Equilibrium | A state that occurs when an object or system is at rest. | 18 | |
| 9580873740 | Dynamic Equilibrium | A state that occurs when an object is moving in a straight line with constant speed. | 19 | |
| 9580873741 | Pulley | A simple machine that consists of a grooved wheel with a rope or cable wrapped around it. Changes the direction of the applied force. Analyze systems of masses and pulleys as entire systems and/or as individual objects. |  | 20 |
