# Final Velocity

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Final velocity, abbreviated as $$v_f$$, is the ending point of motion.

## Final velocity formulas

$$\large{ v_f = v_i + a \; t }$$

$$\large{ v_f = 2 \; \bar {v} - v_i }$$

Symbol English Metric
$$\large{ v_f }$$ = final velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
$$\large{ a }$$ = acceleration $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$
$$\large{ t }$$ = time $$\large{ sec }$$ $$\large{ s }$$
$$\large{ \bar {v} }$$ = average velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
$$\large{ v_i }$$ = initial velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
