Kinematics & Dynamics

$\overrightarrow{r},r$ : Position or Seperation $d$, $s$ : Depends. Distance OR Displacement $\overrightarrow{d}$, $\overrightarrow{s}$ : Displacement $△\overrightarrow{d}$, $△\overrightarrow{s}$ : Displacement $v$ : Depends. Speed OR Velocity $\overline{v}$ : Velocity

• ${\overrightarrow{v}}_0$ : Initial Velocity
• ${\overrightarrow{v}}_i$ : Instantaneous Velocity or Initial Velocity
• ${\overrightarrow{v}}_{avg}$ : Average Velocity $a$, $\overrightarrow{a}$ : Acceleration $m$ : mass of orbiting object $M$: mass of orbited object $F_g$, $W$ : Weight $F_{net}$ : Net force $F_f$ : Friction $F_T$, $T$ : Tension $F_{AB}$ : Force that object A exterts on B ${\mu }_s$ : Friction Coefficient(Static) ${\mu }_k$ : Friction Coefficient(Kinetic) $\overrightarrow{\omega }$ : Rotational Velocity $\overrightarrow{p}$ : Linear Momentum

Vectors

$\perp$ : Perpendicular $\parallel$ : Parallel

Digital Nomenclature

$\mid \mid \overrightarrow{x}\mid \mid$ : Vector’s Scalar x : Bold variables are vectors x: Non-bold are scalars $x^{\prime }$ : x prime or final x
