Distance vs. Displacement
Classical Mechanics
Level
1
A particle constrained to one dimension starts at \(x=0\), moves to the right to the point \(x=4\), and then moves to the left to \(x=-2\). If \(a\) is the displacement of the particle after this process and \(b\) is the distance traveled, find \(a+b\).
