Tearing paper is this type of change
What is a physical change?
This subatomic particle has a positive charge.
What is a proton?
The speed of an object in a specific direction.

A push or pull on an object.
What is force?
This type of data includes numbers and units.
What is quantitative data?
A pure substance made of only one type of atom.
What is an element?
Color change, gas production, temperature change, and formation of a precipitate may be signs of this.

What is an electron?
A change in velocity over time.
What is acceleration?
This is the factor that is changed on purpose in an experiment.
What is the independent variable?
A substance made of two or more elements chemically combined.
What is a compound?

What is a homogeneous mixture?
Flammability and reactivity are examples of these.
What are chemical properties?
Atoms of the same element with different numbers of neutrons are called this.
What are isotopes?
This law says an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force.
