Ch. 6
Energy- ability to cause change
Kinetic energy- energy an object has due to its motion
Potential energy- energy that is stored due to an object’s position Law of conservation of energy- energy cannot be created or destroyed but can only be transformed from one form into another Temperature- measure of the average kinetic energy of the atoms in an object Heat- transfer of energy from one object to another due to a difference in temperature Conduction- transfer of energy by collisions between the atoms in a material Convection- transfer of heat that occurs when particles move between regions or objects that have different temperatures Radiation- energy that is transferred by waves

Endothermic reaction- chemical reaction that absorbs heat energy Exothermic reaction- chemical reaction that releases heat energy Catalyst- substance that change the rate of a chemical reaction without any permanent change to its own structure

What is energy?

Forms of energy

Compare and contrast potential energy and kinetic energy.

Ch. 7
Charging by contact- transfer of electric charge between objects in contact Charging by induction- rearrangement of electric charge in an object due to a nearby electric field Insulator- material in which electric charges cannot move easily Conductor- material in which electric charges can move easily Static charge- imbalance of electric charge on an object

Electric charge-

How do electric charges exert forces on each other?

What is an electric field?

How do objects become electrically charged?

Describe how lightning occurs.

Ch. 9
Mineral- inorganic, solid material found in nature that always has the same chemical makeup, atoms arranged in an orderly pattern, and properties such as cleavage, fracture, color, hardness, streak and luster. Rock- solid inorganic material that is made up of 2 or more minerals and can be metamorphic, sedimentary or igneous. Crystal- solid material with atoms...
