Question

F = ma, but why mass isn't dependent on force?

​

Answer 1

Newton's true equation is F =dP/dt This means force equals the rate of change of momentum. Momentum P = mv If we assume mass is constant, the formula becomes F = ma. This assumption that mass is constant is true in most common situations. But not always.

Answer 2

Hi there,

As we know F = ma ,as by the Newton's Second Law of equation.And hence , we can say that Force is not gravity here as it depends on the mass of object .The a is the acceleration factor, a constant, based on the mass of the earth.Gravity only affects Weight and all remains Same.
