A car moves in a straight line so that its position changes at every moment according to the relationship:*(1) = 3t – 41² + t³ Where X is in meters and t is in seconds. 1) What is the position of the car at moments t=1,2,3,4 s? 2) What is the displacement of the car between the moments t=0s and t=4s 3) What is the average velocity between the two moments t=2s and t=4s 4) Calculate the obiect's instantaneous velocity at t=3s
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.
