A collie moves from a coordinate of x=-2m, y= 3m, z=1m to a coordinate of x=5m,y=6m,z=3m in a time of 2 seconds. What was the average speed of the collie during this time? A) 4.2 m/s B)2.1m/s c) 0.85 m/s D) 3.4 m/s e) it is impossible to determine with the information given.
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.
