1. Student Dina thinks the acceleration might be constant but she isn't sure. She collects data and makes the following motion graphs: position (cm) 80 60 40 20 0 0 • 0.2 position vs time 0.4 time (s) 0.6 0.8 velocity (cm/s) 150 100 50 0 0 0.2 velocity vs time 0.4 time (s) 0.6 0.8 1 Do the graphs make sense to you? Explain how they are consistent with each other. What can Dina conclude about the motion of the glider from these graphs?
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.
