Why might understanding continuity be important when modeling real-world planar motion with parametrics?
Smooth transitions without interruption which can indicate consistent behaviors
Discontinuous motion can represent changes in direction or speed even if not physically possible
Discontinued paths are usually preferred in engineering and science since they are simpler to analyze
Discontinuities require advanced calculations for precise models which are not necessary
When describing planar motion using parametrics, what does changing the parameter 't' generally represent?
Alteration in spatial dimensions only without time consideration.
Modification in geometric shapes being described by parameters.
Creation of new variables unrelated to time.
Progression of time throughout the motion.
If the parametric equations and model a particle's planar motion, what is the period of the particle’s path along the x-axis?
