"An object that has an unbalanced force acting on it will accelerate in the direction of that force" falls under which of Newton's Laws?
What is Newton's Second Law

What is 2 mph over the speed limit

In terms of Newton's First Law, how is it that a golf ball hit off the moon would travel on forever until it hits something?
A golf ball hit off the moon because Newton's First Law says that an object at motion will remain at motion unless an unbalanced force acts on the object. So the ball would go on forever because gravity or friction is not a factor and the inertia of the ball will keep it going forever.
