Equilibrium in 2D What does two dimensions (2D) mean in mechanics? In two dimensions, a particle may be considered as existing and being able to move around two-dimensional space rather than in a ...
Equilibrium in 1D What is Newton’s First Law of Motion (N1L)? An object at rest will stay at rest, and an object moving with constant velocity will continue to move with constant velocity, unless a...
