simple device for measuring yourreaction time. It consists of a cardboard strip marked with a scaleand two large dots. A friend holds the strip vertically, with thumband forefinger at the dot on the right in, being careful not to touch the strip. Your friend releasesthe strip, and you try to pinch it as soon as possible afteryou see it begin to fall.The mark at the place where you pinch thestrip gives your reaction time. (a) How far from the lower dotshould you place the 50.0 ms mark? How much higher shouldyou place the marks for (b) 100, (c) 150, (d) 200, and (e) 250 ms?(For example, should the 100 ms marker be 2 times as far fromthe dot as the 50 ms marker? If so, give an answer of 2 times. Canyou find any pattern in the answers?)
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.
