Question

ccording to the law of inertia, if you see an object in motion slowing down, what can you conclude? a. That there must be some external influence acting on it that makes it slow down. b. Nothing; any object in motion left to itself will eventually slow down to a stop.

Answer 1

a)

Explanation:

Newton's First law (aka law of inertia) says that any object, not subject to an external influence, must be keep in its present motion status (at rest or moving at constant speed along a straight line) forever.

So, if we see an object in motion slowing down, there must be an external infuence acting on it, that makes it slow down, like a friction force, for instance.
