Newton's Second Law (F = ma)
F = m·a
What it means
Newton's second law links the net force on an object to its mass and acceleration — the core equation of classical dynamics.
Variables
| Symbol | Quantity | SI unit |
|---|---|---|
F | force | N |
m | mass | kg |
a | acceleration | m/s² |
Worked example
Given m = 10 kg, a = 3 m/s², solve for F:
F = 30 N
