Its symbol is written in several forms as m/s 2, m·s −2 or ms −2, , or less commonly, as (m/s)/s. [ 1 ] As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity.
It is reported [9] that most passengers rate a vertical jerk of 2 m/s 3 as acceptable and 6 m/s 3 as intolerable. For hospitals, 0.7 m/s 3 is the recommended limit. A primary design goal for motion control is to minimize the transition time without exceeding speed, acceleration, or jerk limits.
The SI unit of acceleration is the metre per second squared (m s ... with v(t) equal to the speed of travel along the path, and ... 1 m/s 2: 100: 3.280 84: 1: 0.101 ...
newton meter squared per kilogram squared (N⋅m 2 /kg 2) shear modulus: pascal (Pa) or newton per square meter (N/m 2) gluon field strength tensor: inverse length squared (1/m 2) acceleration due to gravity: meters per second squared (m/s 2), or equivalently, newtons per kilogram (N/kg) magnetic field strength
The value of the magnitude of an object's four-velocity, i.e. the quantity obtained by applying the metric tensor g to the four-velocity U, that is ‖ U ‖ 2 = U ⋅ U = g μν U ν U μ, is always equal to ±c 2, where c is the speed of light. Whether the plus or minus sign applies depends on the choice of metric signature.
In SI, this slope or derivative is expressed in the units of meters per second per second (/, usually termed "meters per second-squared"). Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the ...

The inward acceleration is 1 metre per square second, v 2 /r. It is subject to a centripetal force of 1 kilogram metre per square second, which is 1 newton . The momentum of the body is 1 kg·m·s −1 .
