### Some articles on proper acceleration, proper, acceleration:

Rindler Coordinates - Relation To Cartesian Chart
... metric In the region, which is often called the Rindler wedge, if g represents the proper acceleration (along the hyperbola x=1) of the Rindler observer whose proper time ... at rest at time T=0 in the inertial frame, and at this time a Rindler observer with proper acceleration gi will be at position X = 1/gi (really X = c2/gi, but we assume units where c=1 ... defining a Rindler coordinate system we have a choice of which Rindler observer's proper time will be equal to the coordinate time t in Rindler coordinates, and this observer's proper acceleration defines ...
Specific Force
... in meters/second² (m·s−2) which is the units for acceleration ... force is not actually a force, but a type of acceleration ... (mass-)specific force is not a coordinate-acceleration, but rather a proper acceleration, which is the acceleration relative to free-fall ...
Applications - Unidirectional Acceleration Via Proper Velocity
... Proper acceleration at any speed is the physical acceleration experienced locally by an object ... In spacetime it is a three-vector acceleration with respect to the object's instantaneously varying free-float frame ... Proper-acceleration is also useful from the vantage point (or spacetime slice) of external observers ...

### Famous quotes containing the word proper:

Discipline isn’t just punishing, forcing compliance or stamping out bad behavior. Rather, discipline has to do with teaching proper deportment, caring about others, controlling oneself and putting someone else’s wishes before one’s own when the occasion calls for it.
Lawrence Balter (20th century)
