2 A small steel ball, dropped from rest, takes 0.50 s to fall through a vertical distance of 1.25 m. Determine (a) the average speed of the ball, AVg Speen=DIT = 1.25/0.5 = 2.5m/s (b) the actual speed of the ball after it has fallen through a vertical distance of 1.25 m, assuming that the acceleration is constant, 2-4 OROON the value of that acceleration. (c)
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.
