A car is traveling north on a city street. It starts from rest at a stoplight and accelerates uniformly at a rate of 1.0 m/s until it reaches the speed limit of 17 m/s. The car will travel at this velocity for 5 minutes and will then decelerate at a uniform rate of 1.4 m/s until it comes to a complete stop at the next stop light. How far apart are the two lights?
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.
