Physics Fundamentals and Measurements Flashcards

Flashcards covering vector operations, fundamental units, standardized measurement systems, and dimensional analysis based on the lecture notes.

Vector Addition ($M+N$)

The result of adding vectors $m = -4i+5j-3k$ and $N=6i+9j+5k$, which is $2i + 14j - 2k$.

Fundamental Units

The core units of measurement which include mass, Time, and Current.

The International System unit

The Unified System of measurement used as a Standard world measurement.

Displacement (Start to Finish)

The change in position of a particle that moves from $x = 6m$ to $x = 100m$ and then back to $6m$, resulting in $0m$.

Pressure (Dimensional Formula)

A dimensionally correct representation defined as $ML^{-1} T^{-2}$.

Viscosity (Dimensional Formula)

A dimensionally correct representation defined as $ML^{-1} T^{-1}$.

Dimensionless

A term describing a value that lacks physical dimension, such that it is equal to $1$.
