The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.

Distance is a scalar measure of an interval measured along a path. Displacement is a vector measure of an interval measured along the shortest path.
The astronomical unit is typically used for stellar system scale distances, such as the size of a protostellar disk or the heliocentric distance of an asteroid, whereas other units are used for other distances in astronomy.
26 Ιουλ 2024 · Figure 3.1.2 shows a particle at time t 1 located at P 1 with position vector →r (t 1). At a later time t 2, the particle is located at P 2 with position vector →r (t 2). The displacement vector Δ→r is found by subtracting →r(t1) from →r(t2): Δ→r = →r(t2) − →r(t1).
The total distance traveled (sum of magnitudes of individual displacements) is $$x_{Total} = \sum |\Delta x_{i}| = 0.5 + 0.5 + 1.0 + 1.75\; km = 3.75\; km \ldotp$$ We can graph Jill’s position versus time as a useful aid to see the motion; the graph is shown in Figure \(\PageIndex{4}\).
