Energy & Heat
THE CAPACITY TO DO WORK
WHAT IS ENERGY?
THE FORCE THAT CAUSES ALL PHYSICAL OBJECTS TO ATTRACT EACH OTHER
WHAT IS GRAVITY?
A DISTURBANCE THAT CARRIES ENERGY BETWEEN LOCATIONS THROUGH A MEDIUM OR SPACE
THE PROCESS BY WHICH A LIQUID BECOMES A GAS
A PROCESS THAT OCCURS WHEN MOLECULES INTERACT TO FORM A NEW SUBSTANCE
WHAT IS A CHEMICAL REACTION?
THE ENERGY OF AN OBJECT DUE TO THE MOTION OF THE OBJECT
ANOTHER TERM FOR NEWTON'S FIRST LAW, WHICH STATES THAT OBJECTS AT REST TEND TO REMAIN AT REST UNLESS ACTED UPON BY AN OUTSIDE FORCE AND OBJECTS IN MOTION TEND TO REMAIN IN MOTION AT CONSTANT VELOCITY UNLESS ACTED UPON BY AN OUTSIDE FORCE
WHAT IS INERTIA?
THE DISTANCE BETWEEN TWO CONSECUTIVE CRESTS OR TWO CONSECUTIVE THROUGHS OF A WAVE
WHAT IS A WAVELENGTH?
TINY PARTICLES OF MATTER
WHAT ARE MOLECULES?
TO SHOW WHAT HAPPENS IN A CHEMICAL REACTION, SCIENTISTS USE THIS
THE FLOW OF HEAT ENERGY BETWEEN SUBSTANCES THAT ARE IN DIRECT CONTACT WITH ONE ANOTHER
INCLINED PLANE, WEDGE, SCREW, LEVER, PULLEY, AXLE AND WHEEL ARE ALL EXAMPLES OF THIS TYPE OF MACHINES
WHAT ARE SIMPLE MACHINES?
THE NUMBER OF WAVELENGTHS PER SECOND
WHAT IS FREQUENCY?
COMBINATION OF TWO OR MORE SUBSTANCES PHYSICALLY INTERMINGLED BY NOT CHEMICALLY BONDED
THIS CHEMICAL SYMBOL REPRESENTS HYDROGEN
A FORM OF HEAT TRANSFER THAT DOES NOT RELY OPON ANY CONTACT BETWEEN HEAT SOURCE AND THE HEATED OBJECT
WHAT IS RADIATION?
SPEED OF AN OBJECT IN A SPECIFIC DIRECTION, USUALLY MEASURED IN METERS PER SECOND (M/S)
WHAT IS VELOCITY?
THE HIGHEST POINT ON A TRANSVERSE WAVE, WHERE THE DISPLACEMENT OF THE MEDIUM IS AT A MAXIMUM
WHAT IS THE CREST?
THE PROCESS IN WHICH THE NUCLEI OF CERTAIN ATOMS BREAK DOWN OVER TIME, RELEASING CHARGED PARICLES OF ENERGY
WHAT IS NUCLEAR RADIATION?
THIS CHEMICAL SYMBOL REPRESENTS CARBON
WHAT IS C?
LOWER LIMIT OF THE THERMODYNAMIC TEMPERATURE SCALE WHERE ATOMS WOULD STOP MOVING ALTOGETHER AND, THEREFORE, IT IS CONSIDERED A PHYSICALLY IMPOSSIBLE TERPERATURE TO REACH
WHAT IS ABSOLUTE ZERO?
POINT AROUND WHICH A LEVER PIVOTS OR ROTATES, FACILITATING MECHANICAL WORK OR FORCE MULIPLICATION
WHAT IS A FULCRUM?
ENERGY THAT TRAVELS BY EITHER WAVES OR PARTICLES, SUCH AS HEAT OR LIGHT
WHAT IS RADIATION?
TINY, NEGATIVELY CHARGED PARTICLES THAT CIRCLE THE NUCLEUS OF AN ATOM
WHAT ARE ELECTRONS?
THIS CHEMICAL SYMBOL REPRESENTS OXYGEN
WHAT IS O?
