Quick Q&A Before You Revise

Is inertia the same as force?

No. Inertia is a property of matter that resists change, while force is an external push or pull that can produce that change.

Why is momentum treated as more than just speed?

Because momentum depends on both mass and velocity. A heavy slow object can have more momentum than a light fast one.
