A particle undergoes three consecutive displacements: (15i + 30j + 12k) cm, d, = (-13i + 15j) cm. Find the components of the (23i-14j-5.0k) cm Your fir %3D d = and ds = (-13i %D the orig %3D resultant displacement and its magnitude. De sions, Solution Three-dimensional displacements are more diffi- cult to imagine than those in two dimensions, because the latter can be drawn on paper. For this problem, let us concep- tualize that you start with your pencil at the origin of a piece of graph paper on which you have drawn x and y axes. Move your pencil 15 cm to the right along the x axis, then 30 cm upward along the y axis, and then 12 cm vertically away from the graph paper. This provides the displacement described by dj. From this point, move your pencil 23 cm to the right parallel to the x axis, 14 cm parallel to the graph paper in to the for ve this n nized The the -y direction, and then 5.0 cm vertically downward to- R. ward the graph paper. You are now at the displacement from the origin described by d + d2. From this point, move your pencil 13 cm to the left in the - x direction, and (fi- nally!) 15 cm parallel to the graph paper along the y axis.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
