Term
 WHAT IS NEWTON'S FIRST LAW?
Definition
 AN OBJECT AT REST OR MOVING AT A CONSTANT SPEED IN A STRAIGHT LINE WILL CONTINUE IN THAT STATE UNTIL AN EXTERNAL FORCE ACTS UPON IT.
Term
 WHAT IS NEWTON'S SECOND LAW?
Definition
 FORCE= MASS X ACCELERATION
Term
 WHAT IS NEWTON'S THIRD LAW?
Definition
 FOR EVERY ACTION, THERE IS AN EQUAL AND OPPOSITE REACTION.
Term
 WHAT IS MASS?
Definition
 THE AMOUNT OF MATTER IN AN OBJECT. DIFFERENT FROM WEIGHT. FROM A PHYSICS PERSPECTIVE, MASS CAN BE DEFINED AS THE RESISTANCE OF AN OBJECT TO ACCELERATION.
Term
 WHAT IS FORCE MEASURED IN?
Definition
 NEWTONS.
Term
 WHAT ARE THE VARIABLES FOR F, M, AND A?
Definition
 FORCE= 1 NEWTON/1KG/1 M/S 2. MASS IS KG. ACCELERATION IS METER PER SECOND SQUARED M/S 2
Term
 WHAT IS THE TERM FOR THE DISPLACEMENT DIVIDED BY THE TIME IT TAKES TO CAUSE THAT DISPLACEMENT?
Definition
 VELOCITY.
Term
 WHAT IS THE FORMULA FOR VELOCITY?
Definition
 AVERAGE VELOCITY= DISPLACEMENT/TIME
Term
 WHAT IS DISPLACEMENT?
Definition
 NET CHANGE IN THE POSITION OF AN OBJECT.
Term
 WHAT DOES AN ARROW OVER DISPLACEMENT MEAN?
Definition
 INDICATE THE VECTOR OF DISPLACEMENT (DIRECTION OF MOTION IS DEFINED).
Term
 WHAT IS THE DISTANCE BETWEEN VELOCITY AND SPEED?
Definition
 VELOCITY INVOLVES DISPLACEMENT (DEFINED VECTOR) OVER TIME. SPEED INVOLVES DISTANCE OVER TIME.
Term
 WHAT IS THE TOTAL LENGTH OF TRAVEL?
Definition
 DISTANCE (ALWAYS A POSITIVE NUMBER)
Term
 WHAT IS THE TERM FOR THE NET CHANGE IN POSITION WITH RESPECT TO A SPECIFIED BEGINNING POINT OF ORGIN WITH A COORDINATE SYSTEM (DIRECTIONALITY)?
Definition
 DISPLACEMENT
Term
 WHAT DOES SCALAR QUANTITY MEAN?
Definition
 HAVE MAGNITUDE ONLY (DISTANCE, HEIGHT, MASS, AND AGE). IN ORDER TO ADD ACALAR QUANTITIS, THE NUMERICAL VALUES OF THE DEFINED MAGNITUDE ARE SIMPLY ADDED.
Term
 WHAT IS RESULTANT?
Definition
 THE SUM OF 2 OR MORE VECTORS ADDED TOGETHER.
Term
 WHAT IS THE FORMULA FOR PYTHAGOREAN THEOREM?
Definition
 A2 + B2 = C2
Term
 WHAT IS A PUSH OR PULL THAT IS DEFINED BY NEWTON'S SECOND LAW?
Definition
 FORCE
Term
 WHAT DESCRIBES HOW VELOCITY CHANGES OVER TIME?
Definition
 ACCELERATION. CHANGE IN VELOCITY DIVIDED BY CHANGE IN TIME
Term
 WHAT IS THE UNIVERSAL ATTRACTION BETWEEN ALL OBJECTS WITH MASS?
Definition
 GRAVITY
Term
 WHAT IS THE TERM FOR THE GRAVITATIONAL FORCE EXERTED ON AN OBJECT BY A MUCH LARGER OBJECT (EARTH)?
Definition
 WEIGHT
Term
 ON THE EARTH'S SURFACE WHAT IS THE FORMULA FOR ACCELERATION?
Definition
 9.8M/S 2
Term
 ACCORDING TO NEWTON'S SECOND LAW IF F=MA, THEN WEIGHT WOULD BE EQUAL TO WHAT?
Definition
 w = MASS X GRAVITY
Term
 WHAT IS THE FORCE PER UNIT AREA?
Definition
 PRESSURE
Term
 WHAT IS THE FORMULA FOR PRESSURE?
Definition
 PRESSURE = FORCE/AREA
Term
 IF YOU ARE INCREASING PRESSURE WHAT DO YOU DO TO FORCE AND AREA?
Definition
 INCREASE FORCE AND DECREASE AREA.
Term
 IF YOU DECREASE PRESSURE WHAT DO YOU DO TO FORCE AND AREA?
Definition
 DECREASE FORCE AND INCREASE AREA
Term
 WHAT ARE 5 UNITS TO MEASURE PRESSURE?
Definition
 PASCAL, TORR, ATM, BAR, AND PSI
Term
 WHAT IS THE PRESSURE EXERTED BY A FORCE OF 1 NEWTON OVER 1 SQUARE METER OF AREA (N/M2).
Definition
 PASCAL
Term
 WHAT IS THE PRESSURE NECESSARY TO SUPPORT A COLUMN OF MERCURY 1MM IN HEIGHT?
Definition
 1 TORR= 1MMHG
Term
 WHAT DOES 1 BAR EQUAL TO?
Definition
 100KILOPASCALS
