For questions 1-5, assume that "forward" is the position direction. 1. A person takes 30 seconds to walk forward 30 meters. Calculate their velocity. 2. A person takes 15 seconds to walk backwards 10 meters. Calculate their velocity. 3. What is the total distance traveled in #1 and #2 combined? 4. What is the total displacement after #1 and #2 combined? 5. Calculate the average speed and the average velocity for #1 and #2 combined (clearly label each calculation)?
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.
