Concept explainers

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.

An object that is free-falling is acted upon by the force of gravity alone.
A falling skydiver which has reached terminal velocity is considered to be in a state of
free fall.
A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT
considered to be in a state of free fall.
An object in free fall experiences an acceleration which is independent of the mass of
the object.
A ball is thrown upwards, rises to its peak and eventually falls back to the original
height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is
downwards.
A ball is thrown upwards, rises to its peak and eventually falls back to the original
height. The speed at which it is launched equals the speed at which it lands. (Assume
negligible air resistance.)
A very massive object will free fall at the same rate of acceleration as a less massive
object.
The value of g on Earth is approximately 9.8 m/s2.
The symbol g stands for the force of gravity.

A free falling object is an object that is falling under the sole influence of
gravity. Any object that is being acted upon only by the force of gravity is
said to be in a state of free fall. There are two important motion
characteristics that are true of free-falling objects:Free-falling objects do
not encounter air resistance. All free-falling objects (on Earth) accelerate
downwards at a rate of 9.8 m/s/s (often approximated as 10 m/s/s for
back-of-the-envelope calculations). Which of the following statements
about free fall and the acceleration of gravity are TRUE? List all that apply.
