3.2: Vectors - Physics LibreTexts
Most commonly in physics, vectors are used to represent displacement, velocity, and acceleration. Vectors are a combination of magnitude and direction, and are drawn as arrows. The length represents the magnitude and the direction of that quantity is the direction in which the vector is pointing.

The resultant displacement is the vector sum of the two displacements experienced during the trip. Since they're perpendicular to one another, the resultant is the hypotenuse of a right triangle. Its magnitude can be found using pythagorean theorem and its direction can be found using the tangent function.

The vector A can be expressed as the sum of two vectors along the x and y axes, A = A x + A y, where A x and A y are called the components of A. The direction of A x is parallel to the x axis, and that of A y is parallel to the y axis.

Key Terms. Key Equations. Summary. 4.1 Displacement and Velocity Vectors. The position function →r (t) gives the position as a function of time of a particle moving in two or three dimensions. Graphically, it is a vector from the origin of a chosen coordinate system to the point where the particle is located at a specific time.

Mar 28, 2024 · Using vectors to describe motion in two dimensions. We can specify the location of an object with its coordinates, and we can describe any displacement by a vector. First, consider the case of an object moving with a constant velocity in a particular direction.
We will begin by introducing the concept of vectors that will allow us to generalize what we learned last time in one dimension to two and three dimensions. In particular, we will define vector addition and subtraction and relate the component representation of a vector to the magnitude and direction representation.
Components of Vectors. One of the most important ideas in vectors is components. Just like a component stereo system is made of several individual parts working together, components of vectors are the individual parts that add up to the overall resultant. Example 1: A car drives 10.0 km [E] and then 7.0 km [N]. Determine its displacement.
3.1 Kinematics in Two Dimensions: An Introduction - OpenStax
For two-dimensional motion, the path of an object can be represented with three vectors: one vector shows the straight-line path between the initial and final points of the motion, one vector shows the horizontal component of the motion, and one vector shows the vertical component of …

Displacement is a vector measure of the interval between two locations measured along the shortest path connecting them. Velocity is the rate of change of displacement with time. Acceleration is the rate of change of velocity with time. Many kinematic problems in Two Dimensions can be solved using synthetic geometry.
2D Motion Position, Velocity, and Acceleration as Vectors
It is important to keep in mind that, although the vector equations for kinematics look almost identical to their scalar counterparts, the range of physical phenomena that they can describe is far greater.
