Although we usually write Newton's second law for one-dimensional motion in the form F=ma, which holds when mass is constant, a more fundamental version is . The simpler form holds only when the mass is constant. Consider an object whose mass is changing, and use the product rule for derivatives to find Newton’s law. Express your answer in terms of the variables m, a, v, and dm/dt.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

step-by-step explanation:
