Use distance to describe the total path between starting and ending points, and use displacement to describe the shortest path between starting and ending points. Measurement from your initial position to your final position is distance traveled, and the measurement of the total length of your path from the starting position to the final ...

Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up. For example, lets say you drive a car. You drive it 5 miles east and then 3 miles west.
3 sty 2023 · The distance formula is derived from the Pythagorean Theorem and is used to find the length of a line segment. See Example and Example. The midpoint formula provides a method of finding the coordinates of the midpoint dividing the sum of the \(x\)-coordinates and the sum of the \(y\)-coordinates of the endpoints by \(2\). See Example and Example.
To find the distance between two points ($$x_1, y_1$$) and ($$x_2, y_2$$), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. The distance formula is $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $
12 sty 2024 · For motion in two and three dimensions, we generally use the coordinates \(x\), \(y\), and \(z\) to locate a particle at point \(P(x, y, z)\). If the particle is moving, the variables \(x\), \(y\), and \(z\) are functions of time (\(t\)): \[x = x(t) \quad y = y(t) \quad z = z(t) \ldotp \label{4.1}\]
12 wrz 2022 · In Figure 4.2.6 we show the vectors →r (t) and →r (t + Δ t), which give the position of a particle moving along a path represented by the gray line. As Δ t goes to zero, the velocity vector, given by Equation 4.2.9, becomes tangent to the path of the particle at time t.
Summary. Linear motion allows us to start exploring kinematics, which is the study of the motion of objects. The topics in this chapter will allow us to answer the questions of how far something goes, how fast it goes, and how quickly it speeds up or slows down in the process.
