WITH A DISTANCE OF 34 KILOMETERS TRAVELED IN A TIME FRAME OF 2500 SECONDS, A LOCAL HIGHWAY DRIVER FINISHED HIS TRAVEL WITH THIS FINAL VELOCITY
27.2 m/s
F = ma
THE LEAD SINGER OF A LOCAL ROCK BAND STARTS AT REST, THEN REACHES A FINAL VELOCITY OF 14 M/S AFTER 9 SECONDS OF RUNNING ACROSS THE STAGE. WHEN ROUNDED TO THE NEAREST TENTH, HE REACHED THIS ACCELERATION
1.6 m/s2
IT'S THE FUNDAMENTAL UNIT FOR MASS, ALTHOUGH THE UNIT ITSELF IS NOT A BASE UNIT
Kilograms
IF YOU USE SPEED, ONLY WORRY ABOUT DISTANCE. IF YOU USE VELOCITY, WORRY ABOUT TWO FACTORS: DISTANCE AND THIS
Direction
A CRUISE SHIP TRAVELED FROM A DOCK IN THE CARIBBEAN TO A DOCK IN MAINLAND NORTH AMERICA; GOING AT A CONSTANT VELOCITY OF 30 MILES PER HOUR AND TAKING 7 HOURS, THE TWO DOCKS WERE THIS MANY METERS APART
336000 m
IT IS DEFINED AS AN OBJECT'S TENDENCY TO RESIST CHANGE IN MOTION
Inertia
A 98 KILOGRAM WISE MAN SAT ON HIS THINKING ROCK ON EARTH, PRODUCING THIS MUCH FORCE ON THE ROCK
960.4 N
IT'S THE UNIT FOR FORCE, SYMBOLIZED BY ONE LETTER AND ALSO NAMED AFTER A FAMOUS PHYSICIST
Newtons
FORCE OF GRAVITY IS ONE WAY TO SAY IT, THIS IS ANOTHER WAY TO SAY IT
Weight
A SHOPKEEPER USES A FORCE OF 98N TO PULL A SHOPPING BAG ON THE COUNTER, DISPLACING THE BAG BY 4.3 METERS AND CAUSING THE SHOPKEEPER TO DO THIS MUCH WORK
421.4 J
WHEN YOU HAVE TOO MANY WATTS, OR DEALING WITH THE POWER OF A CAR, DIVIDE YOUR WATTS BY 746 AND YOU GET THIS ALTERNATIVE MEASUREMENT OF POWER
Horsepower
A JUVENILE DROVE HIS VEHICLE 97 KILOMETERS SOUTH IN 2.1 HOURS BEFORE CALLING IT QUITS. ROUNDED TO THE NEAREST HUNDREDTH, HE REACHED A FINAL VELOCITY OF THIS
25.66 m/s South
IT SOUNDS LIKE THE NAME OF A FORTNITE CHARACTER, BUT IT'S ACTUALLY THE UNIT FOR WORK
Joules
DON'T GET THESE TWO TERMS MIXED UP; ONE OF THEM, DISTANCE, IS A SCALAR QUANTITY. THE OTHER, DISPLACEMENT, IS THIS
Vector quantity
TWO SCIENTISTS, ONE WEIGHING 82 KILOGRAMS AND THE OTHER WEIGHING 73 KILOGRAMS, STAND 0.4 METERS APART AND ATTEMPT TO FIND THEIR FORCE OF ATTRACTION, GETTING THIS ANSWER WHICH THEY ROUNDED TO THE NEAREST TENTH
2.5e-6 or 2.5*10-6
TWO COMMON FORMS OF ENERGY RESIDE IN MECHANICAL ENERGY; ONE OCCURS WHEN AN OBJECT IS IN MOTION, BUT THIS ONE IN SPECIFIC OCCURS WHEN THE ENERGY IN AN OBJECT IS STILL STORED AND HAS YET TO BE RELEASED
Gravitational potential energy
A MAN TRIES TO FIND THE FORCE IN POUNDS THAT HE EXERTS ON A CRATE, WHEN THE CRATE HE PUSHES IS 50 KILOGRAMS AND HE PUSHES IT 5 METERS. HE CALCULATES IT AND GETS THIS ANSWER
550 N
IT'S A VARIABLE THAT MEANS MORE THAN JUST FORCE, SPECIFICALLY IT REPRESENTS GRAVITATIONAL FORCE
Fg
THE UNITS OF VELOCITY AND THIS MEASUREMENT ARE ALMOST SIMILAR; VELOCITY'S UNIT DOES NOT HAVE AN EXPONENT, THIS MEASUREMENT'S UNIT DOES
Acceleration
A 160 POUND RUNNER GOES A DISTANCE OF 5000 KILOMETERS IN 45 MINUTES. WHEN HE TRIES TO USE THESE TO SOLVE FOR HIS POWER, HE ROUNDS THE ANSWER TO THE NEAREST TENTH AND GETS THIS
1847.5 W
WHEN TWO FORCES ON AN OBJECT ARE BALANCED OUT, THIS VECTOR SUM IS ALWAYS ZERO
Net force
A 4000 POUND CAR TRAVELS WITH AN ACCELERATION OF 23 M/S2 , GOING A DISTANCE OF 15000 METERS IN 37 MINUTES. ROUNDING TO THE NEAREST HUNDREDTH, THE CAR USED THIS MUCH POWER
282555.28 W
G
THE VARIABLE "W" CAN MEAN MORE THAN ONE THING IN SCIENCE; THE "W" CAN EITHER MEAN WATTS OR THIS
