A runner practices along a straight line 2000 m long, running back and forth until she returns to the starting point of the course. With the information provided we can ensure when considering the entire route (outbound trip plus return trip): a) During the tour he had a positive average speed, but there is not enough information to infer something about his average speed. b) During the tour he had a positive average speed and his average speed was zero. c) During the trip he had an average speed equal to zero and his average speed was positive. d) We need to know the time it took the runner back and forth to be able to infer something about her average speed and average speed.
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.
