A student rolls a marble across a table and off the edge. At the instant the marble leaves the edge of the table, she drops, from rest, a second marble straight down from the same height. Consider the following statements about the motion of the marbles: I. Both have equal accelerations. II. Both strike the floor at the same time. III. Both have the same velocity at the instant they strike the floor. If air resistance is ignored, which statement(s) is(are) true? Question 2 options: I only II only III only I and II only 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.
