Chapter 2 - Newtonian Mechanics
| Term | Definition |
|---|---|
| Force | push or pull on an object; = ma; kgm/s^2 = N |
| Mass | m; scalar; inertia; kg |
| Weight | = mg; vector; gravitational attraction to the Earth; N |
| Newton's First Law | a body at rest or in motion with constant velocity will remain that way unless acted upon by a force |
| Newton's Second Law | F = ma; F direction = a direction |
| Newton's Third Law | For every action, there is always an equal but opposite reaction; Fba = -Fab |
| Gravitational Force Eq | F = Gm1m2/r^2 |
| Translational Eq | Sum of the force vectors equals 0 |
| Rotational Eq | Torque |
| Torque Equation | T = rFsin theta |
| Torque in clockwise direction is... | negative |
| Find max Torque at | sin 90 degrees cuz it = 1 |
| Static Friction | force which must be overcome to set an object in motion; opposes motion; to get object moving from rest |
| Kinetic Friction | to keep object moving; (mu)(F normal) |
| When two blocks are connected on conveyor belt... | their acceleration is equal and their tensions are equal; add equations together to find acceleration and Tension |
| Uniform Circular Motion Acceleration and Force Equations | a = v^2/r; F centripetal = (mv^2)/r = ma |
