A particle’s motion along the x-axis is given by the equation x = 2t2 - 3t, where x is in cm and t is in seconds. Part A The particle’s position at t = 2 s is: -2.0 cm (Not enough information) 2.0 cm 0.0 cm SubmitRequest Answer Part B The particle’s velocity at t = 1 s is: 2.0 cm/s (Not enough information) 4.0 cm/s 1.0 cm/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.
