# How to find the rate of acceleration?

Jul 10, 2018

It depends on what data you have. See below.

#### Explanation:

You probably were given a set of 4 formulas of motion. The three that include acceleration are

• $v = u + a \cdot t$
• $d = u \cdot t + \frac{1}{2} \cdot a \cdot {t}^{2}$
• ${v}^{2} = {u}^{2} + 2 \cdot a \cdot d$

$v$ is final velocity, $u$ is initial velocity,
$d$ is displacement (or distance), and $a$ is acceleration

Newton's 2nd Law is another formula which involves acceleration. In formula form (Newton described it in words) it is

$F = m \cdot a$

$F$ is force, $m$ is mass

To use this set of formulas to find acceleration, choose the formula that has a place for the data you have. Plug the data into the appropriate places and solve for $a$.

I hope this helps,
