Acceleration(Velocity,British: acceleration) IsUnit timePer hitspeed OfRate of change(SpeedTime derivative[Note 1]).Acceleration is defined as a vector that indicates the temporal change of the velocity vector.[1].


Acceleration as a vectorparallelogram OflawIt is possible to synthesize and decompose with, as in the case of force and speed,NormalAcceleration,TangentAccelerationOften decomposed into.Normal acceleration changes direction, tangential accelerationSpeedchange.

In generalDecelerationWhat is called (Gensokudo) isnegativeIt is the acceleration (opposite the direction of travel).Also, changing (turning) the direction of travel means receiving acceleration in a direction different from the direction of travel.

If the position coordinates are x (0) = 0, the following equation with t eliminated can be obtained by transforming the above two equations.[3].
