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.
Supply what is asked with the correct integer values, i.e. no decimal places. Do not forget the negative sign (-) if needed.
The position vs. time graph of a moving particle for a time interval of 23 seconds is shown below. Each square unit in the horizontal axis corresponds to one second, and each square unit in the vertical axis corresponds to one meter.
a. What is the instantaneous velocity of the particle at t = 11 s? __ m/s
b. What is the average velocity of the particle from t = 17 s to t = 18 s? __ m/s
