Your friend drops a meterstick and then you catch it. You repeat this 5 times, writing down how far the stick has fallen each time. You get 7.0 cm, 16.0 cm, 13.0 cm, 7.0 cm, and 12.0 cm. What is your average reaction time for this experiment? Take the average by first determining the times which correspond to each distance, and then averaging these times. Your average reaction time is _________ seconds. (Answer with at least 2 significant figures.)
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.
