An object moving in the $+x$ direction experiences an acceleration of $+2\mathrm{.}0\frac{m}{s^2}.$ This means the object

is traveling at $2\mathrm{.}0\frac{m}{s}.$

is decreasing its velocity by $2\mathrm{.}0\frac{m}{s}$ every second.

travels $2\mathrm{.}0$ m in every second.

is increasing its velocity by $2\mathrm{.}0\frac{m}{s}$ every second.An object moving in the $+x$ direction experiences an acceleration of $+2\mathrm{.}0\frac{m}{s^2}.$ This means the object
