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.
Two particles A and B move with constant velocity about the same axis ?̂ in the opposite direction. opposite such that at t = 0 s when particle B passes through Q its velocity is 5.0 m/s;
particle A passes through point P, it has a velocity of 6.0 m/s. The distance between the points P and Q is 142 m. Determine the constant decelerations which must be applied by both particles stop simultaneously to avoid collision (when they stop the distance between the particles is zero). between the particles is zero).
