1. Suppose a particle is moving at a varying velocity along a straight line and that s = f(t) represents the distance of the particle from a point as a function of time t. a. Sketch a possible graph for f so that the average velocity of the particle between t = 0 and t = 3 is positive. b. Sketch a possible graph for f so that the instantaneous velocity at t = 7 is 0 and the instantaneous velocity at t = 8 is negative.
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.
