One acceleration, four writings

Scrub the particle. Every acceleration writing equals the same live a — which form is natural depends on whether you were given v(t) or v(x).

All writings below equal this number

v against t · natural for dv/dt

v against x · natural for v dv/dx

Both graphs are the same particle. Drag either curve (or the mass) · Play to animate
