1) Pheromone is a substance emitted by ants while they travel so that others may be able to follow exactly the same direction as the others took. If a zoologist is to measure the distance the ant travels and in what particular direction does it take, how would this quantity be classified? A. Equilibriant B. Magnitude C. Scalar D. Vector 2) Which of the following statements regarding vectors and scalars is INCORRECT? A. A scalar quantity may be either positive or negative. B. A vector that is zero may have components other than zero. C. It is possible to use vector components that are not perpendicular. D. Two vectors are equal only if they have the same magnitude and direction.
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.
