Someone in a skyscraper drops an egg on the boss’s car. The boss is mad. He asks you to investigate. You discover that a running video camera in the building recorded the egg passing by a 20th floor full-length window that is 3.00 m from ceiling to floor. Reviewing the tape you notice it takes 0.20 s for the egg to pass the window. Each “story” or “floor” of the building is 4.00 m. (a) From how high above the top of the window was the egg dropped? (From which floor?) (b) With what speed did the egg hit the car’s roof? (which was level with the floor of the 1st floor)
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.
