Chemical Reactions
This is the energy stored in chemical bonds
Chemical energy
Every science relies on this type of science
Physics
This is a point against which motion is measured
Reference point
Accurate directions include these two things
distance and direction from starting point
This tells you how quickly an object travels in relation to a reference point
speed
This is a chemical reaction in which a substance reacts rapidly with oxygen, often producing heat and light
Combustion reaction
This type of scientist investigates the laws that govern space, time, force, motion, matter, and energy
Physicist
He listed the presence of motion as one of his five arguments for the existence of God
Thomas Aquinas
this is the term in physics that means size or quantity
magnitude
This tells you how quickly and in what direction an object is moving
Velocity
This is a chemical reaction in which a compound breaks down into two or more simpler substances
decomposition reaction
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
This refers to using a reference point to detect motion. hint... part of its name is in this statement.
When a physical measurement does NOT carry information concerning direction, we call it this:
scalar
This is described in units of distance and time
speed
This is a chemical reaction in which two or more substances react to form a single compound
Synthesis reaction
This is one of the most important concepts in all of physics (it pertains to motion)
All motion is relative
This is the length of a path between two points. It does not need a reference point and does not need direction.
Distance
When a physical measurement does carry information concerning direction, we call it this:
vector
This is the ratio of the total distance traveled to the total time of the trip
average speed
*DOUBLE JEOPARDY*$1000 points*
-Chemical Reactions that release energy to its surroundings are this:
-Chemical Reations that absorb energy are this
Exothermic
Endothermic
Physics is the study of these types of laws of the universe
natural
This is the change in the position of an object
*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
This is the rate at which an object is moving at a given moment in time
instantaneous speed
