Apologia Physical Science Mod 5 and Mod 6 Review

Chemical Reactions

100

This is the energy stored in chemical bonds

Chemical energy

200

This is a chemical reaction in which a substance reacts rapidly with oxygen, often producing heat and light

Combustion reaction

300

This is a chemical reaction in which a compound breaks down into two or more simpler substances

decomposition reaction

400

This is a chemical reaction in which two or more substances react to form a single compound

Synthesis reaction

500

*DOUBLE JEOPARDY*$1000 points*
-Chemical Reactions that release energy to its surroundings are this:
-Chemical Reations that absorb energy are this

Exothermic 

Endothermic

FUNdaMENTAL

100

Every science relies on this type of science

Physics

200

This type of scientist investigates the laws that govern space, time, force, motion, matter, and energy

Physicist

300

This is the branch of physics that deals with analyzing and understanding objects in motion, forces applied to those objects, and the energy that exists in them. 

Mechanics

400

This is one of the most important concepts in all of physics (it pertains to motion)

All motion is relative

500

Physics is the study of these types of laws of the universe

natural

I like to move it!

100

This is a point against which motion is measured

Reference point

200

He listed the presence of motion as one of his five arguments for the existence of God

Thomas Aquinas

300

This refers to using a reference point to detect motion.  hint... part of its name is in this statement.  

Frame of reference

400

This is the length of a path between two points.  It does not need a reference point and does not need direction. 

Distance

500

This is the change in the position of an object

Displacement

Are you displaced?

100

Accurate directions include these two things 

distance and direction from starting point

200

this is the term in physics that means size or quantity

magnitude

300

When a physical measurement does NOT carry information concerning direction, we call it this:

scalar

400

When a physical measurement does carry information concerning direction, we call it this:

vector

500

*DOUBLE JEOPARDY*$1000 POINTS*
Distance and Displacement are similar in this manner;  and different in this manner

-both refer to the length between two points
-displacement includes directional information;  distance does not

Speed or Velocity

100

This tells you how quickly an object travels in relation to a reference point

speed

200

This tells you how quickly and in what direction an object is moving

Velocity

300

This is described in units of distance and time

speed

400

This is the ratio of the total distance traveled to the total time of the trip

average speed

500

This is the rate at which an object is moving at a given moment in time

instantaneous speed
