Question

if you know the force applied to an object and measure its acceleration, which equation would you use to calculate the object’s mass?
○ m = fa
○ m = af
○ m = a/f
○ m = f/a

Explanation:

Step1: Recall Newton's second law

The core formula is $F = ma$, where $F$ is force, $m$ is mass, $a$ is acceleration.

Step2: Isolate mass $m$

Divide both sides of the equation by $a$ to solve for $m$.
$\frac{F}{a} = \frac{ma}{a}$
Simplify to get $m = \frac{F}{a}$

Answer:

○ $m = F/a$
