A passenger bus starts from a stop and travels with a uniform acceleration of 0.6m/s 2 for 20s until it reached a maximum velocity. It travels with this maximum velocity for another 40s, the brake is then applied so that a uniform retardation is obtained and then come to a halt at the next bus stop after 10s. Sketch the velocity-time graph of this motion and use this to calculate the total distance.
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.
