10 cards from this deck
v=dxdtv = \frac{dx}{dt}v=dtdx or v=x˙v = \dot{x}v=x˙
dxdt\frac{dx}{dt}dtdx (differentiation w.r.t. time)
∣v∣|v|∣v∣ (absolute value of velocity)
Velocity equals zero (v=0v = 0v=0)
a=d2xdt2=x¨a = \frac{d^2x}{dt^2} = \ddot{x}a=dt2d2x=x¨
Displacement and velocity (have direction, can be negative)
Distance and speed (magnitudes only, always positive or zero)
m/s² or ms⁻² (metres per second, per second)
0 (approaches zero)
a=dvdt=v˙a = \frac{dv}{dt} = \dot{v}a=dtdv=v˙
