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
