Why are vectors particularly useful for describing motion in real-world scenarios?
They simplify calculations by ignoring direction.
They allow for describing motion along a single axis only.
They enable the description of motion in any direction, not just two.

In physics, what are the horizontal and vertical parts of a vector called, and how are they related to trigonometry?
They are called scalars and are unrelated to trigonometry.
They are called components and can be found using sine and cosine functions.
They are called axes and are only used for 1D motion.
They are called magnitudes and are found by adding the vector's length and angle.
