To calculate net force using Newton's second law, start with the equation Fnet = Ft + Fg. To isolate mass, move all mass-related terms to one side and factor out m. Then, divide both sides by the coefficient multiplying m to solve for it. The correct formula for mass can be expressed as m = Ft / (a - g). Proper algebraic manipulation is essential for accurate calculations.

How do I isolate the mass?

Newton's second law

Fnet= Ft + Fg
ma= Ft + mg

Thank You

Welcome to PF,

Just follow the rules of algebra. A good first step is to move all terms that have the mass in them to one side of the equation. Factor out m from these terms, and then divide both sides of the equation by the stuff that multiplies m, so that m is now by itself.

Thanks :smile:
 
So it would be like

m=Ft/a-g

Am I right?

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
