What is the Newtonian Notation for velocity and acceleration?

## Part 1#

Choose the best answer.

• Velocity is $$v$$, $$\dot x$$; Acceleration is $$a$$, $$\dot v$$, $$\ddot x$$.

• Velocity is $$\dot v$$; Acceleration is $$\dot a$$.

• Velocity is $$\ddot v$$, $$\dot x$$; Acceleration is $$\ddot a$$, $$\dot a$$.

• Velocity is $$\ddot x$$, $$v$$; Acceleration is $$\dot x$$, $$\ddot v$$, $$a$$.
