A mobile starts from rest at t = 0 s and moves in the positive direction of the horizontal x axis with constant acceleration. The object travels a distance of d 15 m from the instant ta =4 s to tb 8 s. What is the magnitude of the acceleration of the mobile? Note: Remember that the mobile starts to accelerate from t-0s and it maintains that acceleration
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.
