The position of a cat running from a dog down a dark alley is given by the values of the table. t (seconds) 0 1 2 3 4 5 s (feet) 0 13 28 73 87 117 A. Find the average velocity tor the time period beginning when t = 2 and lasting 45 1.3 s 29.5 2.2 s 29.67 3.1 s B. Estimate the instantaneous velocity when t = 2 by finding the average velocity from t = 1 to t = 3: 30
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.
