Newton's Second Law:
| From: | To: |
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The law is mathematically expressed as F = m × a, where F is force in newtons, m is mass in kilograms, and a is acceleration in meters per second squared.
The calculator uses Newton's Second Law equation:

Rearrangements:
Explanation: Enter any two known values to calculate the third unknown variable. The calculator automatically determines which variable to solve for based on the inputs provided.
Details: Understanding force calculations is fundamental in physics, engineering, and everyday applications. It helps in designing structures, analyzing motion, calculating thrust requirements, and solving practical mechanical problems.
Tips: Enter any two of the three variables (force, mass, acceleration). Leave the variable you want to calculate empty. All values must be positive numbers. The calculator will automatically compute the missing value using the appropriate formula.
Q1: What are the standard units for this calculation?
A: Force in newtons (N), mass in kilograms (kg), and acceleration in meters per second squared (m/s²).
Q2: Can I use different units?
A: Yes, but you must convert to the standard units first or adjust the calculation accordingly for consistent results.
Q3: What if I get a division by zero error?
A: Ensure that mass and acceleration are positive values when calculating force, and that acceleration is positive when calculating mass.
Q4: How accurate is this calculation?
A: The calculation is mathematically exact for ideal conditions. Real-world applications may require considering additional factors like friction and air resistance.
Q5: Can this be used for rotational motion?
A: For rotational motion, use the analogous equation τ = I × α, where τ is torque, I is moment of inertia, and α is angular acceleration.
