An athlete swims the length L of a pool in a time t1 andmakes the return trip to the starting position in a time t2. Ifshe is swimming initially in the positive x - direction, determineher average velocities symbolically in (a) the first halfof the swim, (b) the second half of the swim, and (c) theround trip. (d) What is her average speed for the roundtrip?
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.
