(a) Find the average velocity from to m/s (b) Find the average and instantaneous velocity from to 4. average instantaneous m/s m/s (c) Find the approximate instantaneous velocity at t = 3.0 s. m/s (d) Find the average velocity on the open interval from to average m/s and instantaneous velocity at t = 9.2 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.
