Newton's 1st Law
Balanced Forces Particle Model
| Term | Definition |
|---|---|
| Force | an interaction between objects (push or pull) |
| Vector Free Body Diagram | diagram showing all force vector acting on an object |
| Weight (Fw) | non-contact force that acts towards the center of the massive object (planet like) |
| Normal Force (Fn) | contact force that acts perpendicular to the surface due to the compression of atoms in the surface. |
| Friction Force (Ff) | contact force that acts parallel to the surface but opposite to the motion. atoms are sheared and crunched |
| Tension Force (Ft) | Contact force along a rope, string, cable, chain... |
| Spring Force (Fk) | Contact force along the spring due to the compression or expansion of a spring. |
| Newton [N] | Unit of force |
| Net force (Fnet) | The sum (addition) of all forces acting on an object |
| Inertia | the property of matter that resists a change in motion |
| Balanced Forces | Fnet=0, no change in motion, rest of constant motion |
| Unbalanced Forces | Fnet= #, change in motion, acceleration |
| terminal velocity | an object falling at a constant velocity |
| mass | amount of inertia in an object [kg] |
| equilibrium | balanced |
| momentum | inertia in motion [kg*m/s] |
| Applied Force (Fa) | general label for forces that causes a push or pull |
| Thrust Force (F thrust) | force caused by rockets/ exhaust |
| Buoyant Force (Fb) | Force caused by floating |
| Lift Force (Fl) | Force applied to bottom of wings to fly |
