The two dots on top of the "'x "'position vectors denote their second derivative, or their acceleration vectors.
12.
One way to see this is to observe that the magnitude of the acceleration vector is just the path curvature of the corresponding world line.
13.
In general, the added mass is a second-order tensor, relating the fluid acceleration vector to the resulting force vector on the body.

Find the acceleration vector of the particle at the point ( 1, 0 ) . talk ) 11 : 44, 2 November 2011 ( UTC)
15.
The actual acceleration vector would be found by adding thrust per mass on to the gravity vector and the vectors representing any other forces acting on the object.
16.
Siacci's theorem in dynamics is the resolution of the acceleration vector of a particle into radial and tangential components, which are generally not perpendicular to one another.
17.
1908 : Hermann Minkowski denotes the second derivative x, y, z, t with respect to proper time as " acceleration vector " ( four-acceleration ).
18.
Similarly, the angular acceleration vector points along the axis of rotation in the same direction that the angular velocity would point if the angular acceleration were maintained for a long time.
19.
1909 : Max Born denotes the motion with constant magnitude of Minkowski's acceleration vector as " hyperbolic motion " ( ), in the course of his study of rigidly accelerated motion.
20.
The gravitational gradient of the Earth, that is, the change in the gravitational acceleration vector from one point on the Earth s surface to another, is customarily measured in units of eotvos.
