Newton's 2nd Law can be symbolized as EF = ma Let mass A = 100 kg Let mass B = 1 kg What is true about an object of large mass versus an object of small mass? The more massive object has more inertia. The objects have the same inertia. The more massive object has less inertia. The objects have the same weight near Earth's surface. The more massive object has a larger weight near Earth's surface. V If the same net force is applied to both then the larger mass has the larger acceleration. O If the same net force is applied to both then the objects will haye the same acceleration. O If the same net force is applied to both then the larger mass has the smaller acceleration.
