I hope I posted this in the right section. Here are two questions I have. 1) If I pull on a very heavy object, that object's mass resists my attempt to accelerate it. This is known as inertia. When that object resists my attempt to accelerate it, it essentially pulls back on me with an equal force, correct? 2) Earth's gravity pulls on the moon. That pull accelerates the moon. The moon's mass resists that acceleration (inertia). When the moon's mass resists that acceleration with its inertia, does that cause the moon to pull back on the earth with an equal force?
