For questions 2 & 3, use the following problem: An object moves on a straight line so tha after t seconds its distance in millimeters (mm) from its original position is given by x(1) =1² – 21 . 2. Find the acceleration at t = 3: 1 mm/sec? В. 2 mm/sec? C. 0 mm/sec? А. D. 4 mm/sec? Е. 6 mm/sec? F. None of these. 3. At what time does the object change direction? A. t=1 sec B. t= 2 sec C. t= 0.5 sec D. t=4 sec E. Never F. None of these.
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.
