2. It's Friday, and a physics student slowly walks towards the back of class at 1 m/s for 9 sto leave for the weekend. She suddenly realizes that she forgot her backpack under her chair in the front row, and runs back to her seat at 3 m/s to get it. Then she quickly walks at 2 m/s out the back door to catch her bus. A. Draw a motion diagram for this student. B. Carefully graph the position-vs-time for this student. C. Carefully graph the velocity-vs-time for this student.
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.
