Problem 3 Complete the table with the signs of the velocity and acceleration at t = 1 s, t = 3 s and t = 6 s. For 142 s the graph is a horizontal line and for t> 5 s the graph is a straight line. Answer either +, - or 0. x (m) 6 t = 1 s t=3s t=6s Sign of v Sign of a 4 2 -1 2 3 5 6 7 t (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.
