the unpredictable fluctuations or variations that occur when making measurements.

Horizontal displacement from launch to landing.

refers to the measurement of how something changes or progresses over time.

often expressed as a ratio of two different quantities, such as distance over time or change in a variable over time.

Time between detecting a situation and responding.

An evaluation of whether an answer’s sign, size, units and meaning are plausible.

a set of coordinates and axes that serve as a point of reference for describing the position, motion, and interactions of objects.

A fixed object or location used to determine whether an object is moving.

the ratio of the absolute uncertainty of a measurement to the magnitude of the measured quantity itself.

often expressed as a percentage or a decimal, providing a standardized way to compare the uncertainty of different measurements.

Motion described with respect to another object or reference point.

The velocity of one object measured relative to another.
