I am new to physics.
I’m confused about how an bullet shot horizontally would land at the same time with as a bullet dropped vertically (ignoring air resistance and the curvature of Earth).
Having just learnt about inertia previously, I am confused: Why wouldn't it take time for gravity to overcome the horizontal inertia of the bullet?
Maybe I am confusing momentum with inertia? Does inertia increase with velocity? (I haven't learnt that yet)
EDIT: I realize my mistake now. I saw a video on inertia that explained how cars must first overcome their "forwards inertia" in order to turn. This misled me into believing horizontal/vertical inertia were dependent.
