Physical Science FINAL

Substances before a chemical change are called

• metals

• protons

• reactants

• products

This type of energy comes from things that could fall....

• geothermal

• gravitational

• acoustic

• elastic

GPE =

• force X distance

• mass X gravity X height

• length X width

• work X power

Work is measured in

• joules

• grams

• Kelvin

• amps

The transfer of heat from direct contact

• malleability

• conduction

• convection

• transpiration

feet, tons, miles, and gallons =

• Canadian lengths

• Soviet Units

• SI units

• US Customary

Crest to crest or trough to trough on 2 consecutive waves =

• amplitude

• wavelength

• crest

• double troughs

This means that an experiment actually studied what it was supposed to study. It's accurate

• theory

• reliability

• hypothesis

• validity

This is the WHOLE group you are trying to study (Ex: all chimps)

• population

• sample

• group

• independent variable

This means same throughout

• malleability

• homogeneous

• heterogeneous

• conductivity
