RELATIVE MOTION > Example: ➤ In a boat race, boat A is leading boat B by 38m and both boats are travelling at a constant speed of 168km/h. At t=0, the boats accelerate at constant rates. Knowing that when B passes A, t=8s and VA=228km/h, (a) the determine acceleration of A, (b) acceleration of B, (c) the velocity of B relative to A at the time when B passes A. (d) the relative position of A with respect to B when t=2 s.
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.
