Kinematic Universe. Which of the following is/are ALWAYS TRUE? I. Displacement is a vector quantity that has a magnitude and direction that depends on the path taken. II. Average velocity is equal to instantaneous velocity when the acceleration is zero. III. Instantaneous velocity is the slope of the tangent line in the velocity vs. time graph. O Ill only O I and Il only O I l only O I only
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.
