SUMMARY
The calculation of mass using the formula m = f/a is straightforward when both force and acceleration are non-zero. However, if the net force is 0N or acceleration is 0m/s², the equation becomes indeterminate, as 0/0 does not yield a valid result. In practice, mass is often measured in static situations by comparing it to known masses or through mass take-off techniques. For dynamic scenarios, accelerometers can detect acceleration, but accurately assessing the forces acting on a moving body presents significant challenges.
