| FUNDAMENTAL UNITS (BASIC) ARE USED TO MEASURE THREE DIFFERENT THINGS: | LENGTH, MASS, AND TIME. |
| LENGTH: | DISTANCE BETWEEN TWO POINTS |

| DERIVED UNITS ARE UNITS OF MEASUREMENTS WHICH ARE ___________ OF THE FUNDAMENTAL UNITS | PRODUCTS |
| SIX IMPORTANT DERIVED UNITS IN RADIOLOGIC PHYSICS: | AREA, VOLUME, DENSITY, SPECIFIC GRAVITY, TEMPERATURE, AND MECHANICS |
| AREA: | MEASURE OF A TWO-DIMENSIONAL SURFACE EXPRESSED IN SQUARE UNITS. (L X W) |
| VOLUME: | MEASURE OF THE CAPACITY OF A THREE DIMENSIONAL CONTAINER EXPRESSED IN CUBIC UNITS. |
| DENSITY: | MEASURE OF MASS (AMOUNT OF SUBSTANCE PER UNIT OF VOLUME OF THAT SUBSTANCE) |
| DENSITY MEASURES THE ___________ OF THE PARTICLES WHICH MAKE UP THAT SUBSTANCE | COMPACTNESS |
| SPECIFIC GRAVITY: | THE RATIO OF THE DENSITY OF ANY MATERIAL TO THE DENSITY OF WATER. |
| DENSITY OF WATER | 1.00 |
| IF A SUBSTANCE HAS A SPECIFIC GRAVITY LESS THAN 1.00 IT WILL________ ON WATER. | FLOAT (FOAM PEANUTS ABOVE WATER) |
| IF A SUBSTANCE HAS A SPECIFIC GRAVITY GREATER THAN 1.00 IT WILL____________IN WATER. | SINK (LEAD PELLETS) |
| TEMPERATURE: | MEASURE OF AVG. ENERGY MOVEMENT OF PARTICLES WITHIN MATTER |
| AS TEMP INCREASES, DO THE PARTICLES MOVE AROUND MORE RAPIDLY OR LESS? | MORE RAPIDLY |
| AS TEMP DECREASES, DO THE PARTICLES MOVE AROUND MORE RAPIDLY OR LESS? | LESS |
| THERMOMETER IS CALIBRATED AT WHAT TWO POINTS? | FREEZING POINT OF WATERBOILING POINT OF WATER |
| THREE BASIC SCALES ARE USED TO MEASURE TEMP: | FARENHEITCELSIUS (CENTIGRADE)KELVIN (EXTREME HEAT) |
| TEMPERATURE CONVERSION FORMULA | F-32=1.8C |
| HEAT: | ENERGY ASSOCIATED W/ THE MOVEMENT OF PARTICLES WITHIN AN OBJECT. |
| UNIT OF HEAT: | CALORIE |
| ONE CALORIES IS THE AMOUNT OF HEAT NECESSARY TO RAISE ______ BY ____________. | ONE GRAM OF WATER, ONE DEGREE CELSIUS. |
| HEAT CAN BE TRANSFERRED FROM ONE LOCATION TO ANOTHER BY: | CONDUCTIONCONVECTIONTHERMAL RADIATION |
| HEAT CONDUCTION: | TRANSFER OF HEAT BY PARTICLE MOTION FROM A SOLID OF HIGHER TEMP TO A SOLID OF LOWER TEMP. |
| HEAT CONVECTION: | TRANSFER OF HEAT BY PARTICLE MOTION FROM A LIQUID OR GAS OF HIGHER TEMPERATURE TO A LIQUID OR GAS OF LOWER TEMPERATURE. |
| THERMAL RADIATION: | TRANSFER OF HEAT THROUGH SPACE BY THE EMISSION OF INFRARED RADIATION |
| PART OF PHYSICS THAT DEALS WITH MOVEMENT | MECHANICS |
| TWO DERIVED UNITS USED TO MEASURE THE MOVEMENT RATE: | VELOCITYACCELERATION |
| VELOCITY | RATE OF CHANGE OF POSITION W/ TIME.V=D/T (60MILES PER HOUR) |
| ACCELERATION: | RATE OF CHANGE OF VELOCITY W/TIME |
| FIRST LAW OF MOTION | OBJECT AT REST WILL REMAIN AT REST OR AN OBJECT IN MOTION WILL CONTINUE MOVING AT CONSTANT VELOCITY IN A STRAIGHT LINE UNLESS ACTED UPON BY AN EXTERNAL FORCE. |
| THE FIRST LAW OF MOTION IS ALSO KNOWN AS: | LAW OF INERTIA |
| SECOND LAW OF MOTION: | THE FORCE IS REQUIRED TO MOVE AN OBJECT IS EQUAL TO THE PRODUCT OF MASS OF AN OBJECT AND IT'S ACCELERATION. |
| FORMULA OF FORCE: | F=M X A |
| UNIT OF FORCE: | NEWTON (N) |
| THIRD LAW | FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION |
| WEIGHT | THE PULLING FORCE OF AN OBJECT CAUSED BY GRAVITY |
| WORK W=FXD | PRODUCT OF FORCE AND DISTANCE |
