A baseball was thrown directly up in the air, then falls back to the ground freely. Which of the following statements are TRUE about the baseball's displacement with respect to where it was thrown? I. Displacement is increasing as it goes up, and decreasing as it goes down. II. Displacement is total distance traveled by the ball. III. Displacement is maximum at maximum height. a. I and II only. b. I and III only. c. II and III only. d. I, II, and III
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.
