NT3A-QRT21: POSITION TIME GRAPHS OF TWO The graph at right is of the motion of two children, Ariel and Byron, who are moving along a straight hallway. The vertical axis is not labeled. CHILDREN-KINEMATICS a) If the vertical axis is position, does either child ever change direction? If so, at what time or times does this change in direction occur? Explain. No, both children are going in the Positive side of the vortral gars Ariel Byron -O 4 Ti direction, from the graphies we can tell that they more at differntrates (ariel ing line movement b) If the vertical axis is position, are the two children ever at the same position along the hallwa so, at what time or times? Explain. Yes, at the time when both graphes intersect that is in to The curve are crossing
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.
