Movement at a constant velocity

Vector

a quantity with both a magnitude and a direction (ex. force, distance, and their derivatives)

Motion diagram

Diagram showing the displacement of an object at uniform intervals

Uniformly Accelerated Rectilinear Motion

movement with a constant acceleration

Kinematic equations

Equations used to find the characteristics of objects in motion

Dimensional analysis

process of checking if a series of algebraic processes result on the expected derived unit

Demonstration

Problem type in which well-known facts must be used to reach a forgone conclusion, commenting throughout the process

QED

Acronym used in demonstrations to signify the end of the procedure

Sine

proportion between the opposite leg and hypothenuse of a right triange

Cos

proportion between the adjacen leg and the hypothenuse of a right triangle

Tan

proportion between the opposite and adjacent leg of a right triangle

Scalar

a numerical value or magnitude with no direction (speed, distance, mass, time)

Polar notation

way to represent a vector in verbal language, as [magnitude] [units] at [angle] degrees [above or below] [reference axis]

Cartesian notation

way to represent a vector in mathematical language, as a sum of its components in all axes.

î

unit shorthand for the horizontal component in cartesian notation

j

unit shorthand for the vertical component in cartesian notation

Absolute angle

Angle measured in reference counter-clockwise to +x

([magnitude] [unit], [absolute angle])

abbreviated polar notation

Projectile/ parabolic motion

Motion of an object interacting with gravity only. It will only have horizontal acceleration
