# What conditions are necessary for acceleration to occur?

May 8, 2018

#### Answer:

Essentially only one condition is required: an unbalanced force.

#### Explanation:

Newton's Second Law of Motion can be stated as $a = \frac{F}{m}$, where $F$ is the unbalanced force acting on a mass $m$.

Newton's First Law clarifies that, when there is no unbalanced force acting, there is no acceleration.
