The formula \( F = m \times a \) is one of the fundamental principles of Newtonian physics, known as Newton's Second Law of Motion. This law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Formula:

\[ F = m \times a \]

Where:

• \( F \) is the force in Newtons (N)
• \( m \) is the mass in kilograms (kg)
• \( a \) is the acceleration in meters per second squared (\(\text{m/s}^2\))

Units of Force Worldwide

• Newton (N) - SI Unit
• Pound-force (lbf) - US Customary Unit
• Dyne (dyn) - CGS Unit
• Kilogram-force (kgf) - Engineering Unit
• Poundal (pdl) - FPS Unit

Conversion Factors

• 1 Newton (N) = 0.224809 lbf
• 1 Pound-force (lbf) = 4.44822 N
• 1 Dyne (dyn) = 10^-5 N
• 1 Kilogram-force (kgf) = 9.80665 N
• 1 Poundal (pdl) = 0.138255 N
