how does a fast moving train represent Newton's first law

Answer 1

of motion?

A fast moving train represents Newton's first law of motion because it is an example of an object in motion that will remain in motion unless acted upon by an outside force. This is known as the law of inertia, which states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant speed and in a straight line unless acted upon by an outside force.
