Motion and Kinematics
Reference Systems and Motion
A reference system is a point from which the movement of a body is observed. The temporal reference system indicates the starting time for studying a movement, represented by the letter T, with the SI unit of seconds (s). A body's movement involves changes in its position over time relative to a spatial and temporal reference system. Kinematics is the branch of physics that studies motion.
Position and Trajectory
Position indicates a body's location with respect to a reference system at a given time. The trajectory is the set of points through which a body moves concerning a reference system. Trajectories can be classified as:
- Rectilinear motion: The trajectory is a straight line.
- Curvilinear motion:
