A particle moves in a straight line from a point A to a point B with constant deceleration 1.2 ms-2. The particle takes 6s to move from A to B. The speed of the particle at B is 2 ms-1 and the direction of motion of the particle has not changed. Find a the speed of the particle at A, b the distance from A to B. A train, travelling on a straight track, is slowing down with constant deceleration 0.6 ms-2. The train passes one signal with speed 72 km h-1 and a second signal 25s later. Find a the speed, in kmh-1, of the train as it passes the second signal, b the distance between the signals.
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.
