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.
Your roommate A leaves for her physics class and runs down the sidewalk at velocity vA. You then realize that she forgot her lunch and you get the excellent idea to throw it out the window of your 3rdfloor apartment which is directly above the start of the sidewalk. (You are in another section of the same class and both of you understand
a)What are the components of the velocity of the lunch at the moment it was caught by your roommate?
