Web Animation Scripting - Velocity & Acceleration Flashcards

Vocabulary flashcards covering core velocity, acceleration, vector, and 2D canvas motion concepts from the Web Animation Scripting lecture.

Velocity

The rate of change of position, which describes how an object's position changes over time and incorporates both speed and direction.

Acceleration

The rate of change of velocity.

Vector

A mathematical quantity that has both magnitude and direction, represented as an arrow where the length indicates magnitude and the orientation indicates direction.

Pixels per frame

The standard way speed is defined in web animation, indicating how many pixels away an object will be from its starting position at the end of a single frame.

Interval-based animation

An animation technique used to ensure motion proceeds at a uniform rate, especially when browser frame rates become unstable due to heavy computing or scene complexity.

Velocity on two axes

A technique for moving an object across two dimensions by defining horizontal velocity $v_x$ and vertical velocity $v_y$, which are added to the $x$ and $y$ position properties on each frame.
