Air resistance
What is What is the frictional force air exerts against a moving object
100
A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
What is Electrons
100
either of two units of heat energy.
What is Calorie

All matter exists as solids, liquids, or gases. These are called the states of matter. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING.
What is Change of state
100
A variable (often denoted by y ) whose value depends on that of another.
What is Dependent Variable
200
The force that attracts a body toward the center of the earth, or toward any other physical body having mass
What is gravity

Electromagnetic Radiation
What is a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
200
A thing that is composed of two or more separate elements; a mixture
What is Compound

Independent variable
What is What is a variable (often denoted by x ) whose variation does not depend on that of another.
300
Speed
What is What is each of the possible gear ratios of a bicycle or motor vehicle.
300
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
What is Proton
300
transfer
What is The conversion of one form of energy into another, or the movement of energy from one place to another. Solar panels allow for energy transfer from light energy to heat and electrical energy

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds
What is Physical change
500
Not consistent or having a fixed pattern; liable to change.
What is Variable
