300
The Newton's law that defines inertia.
What is Newton's first Law?
400
These are Newton's three laws.
What is the 1) An object in motion will stay in motion, an object at rest will stay at rest unless acted on by a force. 2) Force = mass x acceleration 3) For every action there is an equal and opposite reaction.

The unit of density and how you would find the density of a regular and irregular object.
What is g/cm3(mL) and for a regular solid (box) you would find the mass and then divide it by the volume by using L x W x H. But for an irregular solid (rock)you would find the mass and then divide it by the volume using liquid displacement?
