Bad Jimmy is at the top of the Center for the Sciences (30 m). He throws a ball straight upward with a speed of 22 m/s. a) How high does the ball go? b) What is the ball’s velocity when it passes Jimmy on the way down? c) How long will it take to hit the ground from when Jimmy threw it? d) What is the ball’s velocity when it hits the ground?
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.
