Why can't we resolve the velocity along the direction of movement of the mass in the first place?

Kinetic energy of the object, but Potential energy of the system: Why is it so?
83770
Kinetic energy doesn't make sense

Why use vectors to describe velocity/force/etc instead of treating magnitude and direction as separate values?
59321
force applied not on the center of mass
