Flashcards for vocabulary review based on lecture notes about physics, including kinematics, motion, velocity, acceleration, and graphs.

Sistema Internacional de Medidas (S.I.)

A system of units based on meter, kilogram, and second, used as a standard for physical measurements.

Meter (m)

Unit of measure for distance or length in the SI system.
