The position of an object moving along an x axis is given by x = 2 + 2t - 5t 2 + 1t 3, where x is in meters and t is in seconds. What is its average velocity for the time interval t = 1 s and t= 3 s ? (Your answer must be in m/s and include 1 digit after the decimal place. Maximum of %2 of error is accepted in your answer.)
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.
