Question

How does acceleration depend on the net force?

Answer 1

By Newton's Second Law, Force = mass*acceleration (F=ma).
To for a, divide by a on both sides.
F = ma
$\frac{F}{a}= \frac{ma}{a}$
The a's cancel.

a = F/m
Acceleration is directly proportional to the force and inversely proportional to the mass.
