Newton's Second Law of Motion is typically expressed with the formula:
\[ F = ma \]
where:
- \( F \) is the net force acting on an object (measured in newtons, N),
- \( m \) is the mass of the object (measured in kilograms, kg),
- \( a \) is the acceleration of the object (measured in meters per second squared, m/s²).
This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
