Consider two friends: Alice on the left and Bob on the right. They run toward each other. Initially the two are 54 m apart. Alice starts at rest and accelerate to the right with constant acceleration of 2 m/s Bob starts at rest and accelerate to the left with constant acceleration of 1 m/s (a) Find the time when they meet. (b) Where 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.
