Newton Second Law
Newton Second Law
\[F = m a\]
Variables
F = net force
m = mass
a = acceleration
Description
What is this formula?
Newton Second Law relates the net force applied to an object with its mass and resulting acceleration. It is one of the fundamental equations of classical mechanics.
When to use it
Use this formula when analyzing motion caused by forces, including vehicle acceleration, machinery movement, engineering systems, and physics problems involving dynamics.
Example
A force of 120 N is applied to a cart with a mass of 30 kg.
Data:
F = 120 N
m = 30 kg
Formula:
a = F / m
Substitution:
a = 120 / 30
Result:
a = 4 m/s²
Applications
Vehicle dynamics, mechanical engineering, robotics, industrial machinery, structural analysis, and physics education.
