Find the net force F = m a from mass and acceleration.
| Force (N) | – |
Use this calculator for Newton’s second law: the net force on an object equals mass times acceleration, in the same direction as a. 1 N is 1 kg·m/s².
F here is the resultant of all forces, not one isolated push. A negative acceleration means the net force points opposite your chosen axis. This is the particle form; a rigid body also needs torque and moment of inertia.
Mass (kg): Inertial mass in kilograms, greater than zero.
Acceleration (m/s²): Acceleration along your axis; negative if it slows down that way.
Force (N): Net force F = m a.
