A ball is equipped with a speedometer and launched straight upward. The speedometer reading four seconds after launch is shown at the right. At what approximate times would the ball be moving upward and display the following speedometer readings? 20 10 40 50 60 Speed m/s 20 10 30 40 20 10 40 50 60 60 Speed m/s Speed m/s Time (s): Time,(s): Tap to Answer Tap to Answer 30 50 30 20
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.
