6. The velocity-vs-time graph for a ball moving purely along a vertical line is shown here. Note that the positive y-direction here is "up". Vy t Draw a position-vs-time graph and a motion diagram and describe in a few sentences what might be happening
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.
Given the ball is moving purely in vertical line, which is along y direction.
The graph shows the velocity time graph.
To draw the vatiation of position of ball with time.
Assumption taken here to draw the graph is that the duration for which the ball have positive velocity and negative velocity is same. And there is a sudsen jump (discontinuity) in the velocity profile. It means the velocity suddenly changes from positive to negative in the graph at tje mid of rhe motion.
