Consider a particle whose motion is given by [x(t),y(t),z(t)] = [−1,3,−2] + t2 ⋅ [4,2,−3], 0 ≤ t ≤ 2 What is the particle's position at t = 0 ? What is the particle's position at t = 2 ? What is the particle's velocity at t=0? What is the particle's velocity at t=2? What is the particle's speed at t=0? What is the particle's speed at t=2?
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.
