21) Which of the following is referring to speed (not velocity): (a) 3 m/s south (b) 3 m/s (c) 55 ft/s (d) 55 ft/s north (e) both b and c (f) both a and d
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.

(a) 3 m/s south (b) 3 m/s (c) 55 ft/s (d) 55 ft/s north (e) both b and c (f) both a and d
22) True or False: With respect to the “Bow Tie” diagram, all angles (in each of the 4 quadrants) are with respect to the Horizon. (Use the diagram shown below)
