Two cars are heading towards one another. Car A is moving with an acceleration of aA = 14 m/s2. Car B is moving with an acceleration of aB = -15 m/s2. The cars are initially at rest and separated by a distance d = 2300 m on the x-axis. At what time, in seconds, do the cars meet? What is the displacement, in meters, of Car A? What is the displacement, in meters, of Car B? Now assume that both cars start with an initial velocity. Car A's initial velocity is v0A = 26 m/s and Car B's initial velocity is vB = -26 m/s. At what time, t2 in seconds, do they meet?
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.
