How to Calculate Maximum Force


It's a central tenet of Newtonian mechanics that force is the product of mass and acceleration. For this reason, a commonly used unit of force, the Newton (N), represents kilogram meters per second squared, the kilogram being a unit used for mass, and meters per second squared being a unit used for acceleration. Because mass and acceleration bear the same relationship to force, either can be derived by finding the quotient of the other and a given force. For example, mass equals the quotient of force and acceleration; acceleration equals the quotient of force and mass. You'll have no trouble finding the maximum force of an object.

Things You'll Need

  • Stopwatch
  • Calculator
  • Determine the mass of the object. For example, you may look in a reference manual and find that your Maserati Tipo 61 weighs 600 kilograms.

  • Use a stopwatch to find how long it takes the object to accelerate from an initial speed to a final speed. For example, it takes 10 seconds for your Maserati to accelerate from 10 to 80 miles per hour.

  • Subtract the initial speed of the object from the final speed of the object and divide by the time it took the object to accelerate. For example, (80-10)/10 = 7.

  • Multiply your answer by 1,609. For example, 7 x 1609 = 11263.

  • Multiply your answer by the weight of the object. For example, 11263 x 600 = 6757800. The maximum force of your Maserati Tipo 61 is 6,757,800 N.
