It’s commonly understood that “It’s not the fall that kills you, it’s the sudden stop at the end.” A few summers ago I was roofing my house – the peak of which is roughly 18 feet above the ground. Let’s say I got so caught up in the joy of shingling, I carelessly stepped off the roof, falling to the pavement. Striking the ground, if my head came to rest over a distance of 8 mm (that distance would be the compression of my skull, BTW), a. What (large!) deceleration would I be experiencing (in m/s2)? b. Over what time interval would that deceleration take place?

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.
