A friend asks you to devise and experiment to determine how fast you can throw a baseball without the use of fancy equipment. In response, you ask your friend to measure the time elapsed from the moment you throw the baseball until the moment the baseball reaches its maximum height. Assuming you throw the baseball straight upward, find the speed at which you threw the baseball if your friend measured a time 2.80 s.
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.
