Web21 sep. 2004 · Inertia is proportional to mass, weight is also proportional to mass, too, so both go together. The difference is that inertia is an inherent property of matter, while weight also depends on gravity. A person weighing on Earth 120 pounds (or 120 kilograms, if you wish) weighs only 40 on Mars and 20 on the Moon. WebNewton's first law says that if the net force on an object is zero ( \Sigma F=0 ΣF = 0 ), then that object will have zero acceleration. That doesn't necessarily mean the object is at …
