Position vs. Time Graphs 9. A toy train moves along a straight portion of track. After two seconds of traveling at constant velocity in the positive direction, its position is 4.0 cm. After three additional seconds of traveling at a different constant velocity in the positive direction, its position is 5.0 cm. It travels an additional 5 seconds at yet a different constant velocity in the positive direction, its position is 10. cm. Which time interval of the journey had the greatest velocity? Justify your answer with calculations based on the data from your graph. 10 6 89 10 9 8 7 6 5 4 3 2 1 0 01 2 3 4 MO 7
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.
