1. What velocity does a freely falling object after 4.0 s if it starts
from rest?

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
