In addition, we have adopted a "pleasure pedal" that allows you to decelerate smoothly by increasing the deceleration due to regeneration simply by loosening the accelerator pedal.

Acceleration

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].

Overview

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.

ThePolar coordinatesWhen expressed in (r, θ), the radial and angular components are respectively.

Becomes

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.

Centrifugal forceAcceleration byCentrifugal accelerationThat.

objectAcceleration is applied toPowerIs equivalent to adding (Second law of movement).

The rate of change of acceleration per unit time is jerk orJerkIs called.

Constant acceleration motion

Constant acceleration

When the velocity v (t) and displacement x (t) after the elapsed time t are

Required by[2].

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

unit

Of accelerationunitTo m / s2(Meters per second squared) Is used,EarthquakeFor the acceleration of shakingGal The unit (Gal) is used (100 Gal = 1 m / s)2).

Standard gravityThere is a unit called G (G) based on 1.0 G = 9.806 65 m / s2.
