What is it called when a substance changes into one or more new substances with different properties from the original substance?
Chemical change
What is the law that states an object at rest tends to stay at rest and an object in motion tends to stay in motion unless an unbalanced force acts upon it?
Law of Inertia
Which object will have more inertia - an object with greater mass or an object with smaller mass?
The object with greater mass
What particles make up the nucleus?
Protons and neutrons
What are the horizontal rows on a periodic table called?

What is the law that states that matter is neither created nor destroyed, only changed?
Law of Conservation of Mass
Which law states that for every action there is an equal and opposite reaction?
Law of Action/Reaction
What is the term for a push or a pull on an object that has the ability to change its motion?
