# Newton’s Second Law

Newton’s Second Law is symbolically written as

$\vec{F}_{net} = m \vec{a}$.

Here, $\vec{F}_{net}$ is the net force on an object with nonzero mass $m$. If the object has a mass of zero, such as a photon, Newton’s second law indicates that the net force on the object would be the zero vector. If the mass is nonzero, the object subject to a net force experiences an acceleration $\vec{a}$.

The following YouTube video provides an example of how to use Newton’s Second Law.
