UNIT 6:1
WHAT FORCES ACT ON 2 BALLS TO MAKE THEM STOP
FRICTION AND GRAVITY
WHAT FORCE PULLS UP PAPER CLIPS
MAGNETIC FORCE
WHAT BEST DESCRIBES A GRAVIATIONAL FORCE
FORCE THAT PULLS OBJECTS TO EACH OTHER
WHAT TYPE OF FORCE PUSHES A BOAT ON A LAKE
CONTACT FORCE OR AIR RESISTANCE
WHAT FORCE DOES JOHN USE TO WARM HIS HANDS WHEN HE RUBS THEM TOGETHER
FRICTION
A TV ON EARTH WEIGHS 20 POUNDS, WHAT WILL HAPPEN TO ITS WEIGHT ON THE MOON
IT WILL GO DOWN. IT WILL WEIGH LESS THAN 20 POUNDS
DJ: WHY WOULD AN ASTRONAUT'S WEIGHT BE LESS ON THE MOON
THE MOON HAS LESS GRAVITATION FORCE
3J: THE WEIGHT OF A BOOK IS 12 GRAMS. WHAT'S WRONG WITH THIS STATEMENT?
WEIGHT IS MEASURED IN A DIFFERENT UNIT, NOT GRAMS
DJ: WHAT WILL AFFECT THE AMOUNT OF GRAVITY ON AN OBJECT
MASS AND DISTANCE
DJ: WHAT TWO THINGS ARE NEEDED TO HAVE WEIGHT
MASS AND GRAVITY
IF MASS DOES NOT CHANGE, DOES MATTER CHANGE
NO THEY ARE THE SAME THING
WHY DOES MASS STAY THE SAME ON THE MOON BUT WEIGHT CHANGES
MASS IS THE AMOUNT OF MATTER, WEIGHT IS THE AMOUNT OF GRAVITY
THE SUN AND EARTH HAVE GRAVITY. WHAT HAPPENS IF THE EARTH WERE FURTHER FROM THE SUN
GRAVITY WOULD DECREASE
EXPLAIN WHY A BOWLING BALL HAS MORE GRAVITATIONAL FORCE THAN A BALLOON
THE BOWLING BALL HAS MORE MASS
WHICH HAS MORE GRAVITATIONAL PULL, BOWLING BALL OR A MARBLE
BOWLING BALL
WHICH ONE HAS LEAST GRAVITATIONAL FORCE: 2 BOWLING BALLS 5 METERS AWAY OR 2 MARBLES 5 METERS AWAY
2 MARBLES 5 METERS AWAY
DJ: WHAT IS THE LAW OF GRAVITY
EVERY OBJECT EXERTS GRAVITY ON EVERY OTHER OBJECT
NEWTONS
ARE MASS AND WEIGHT THE SAME? EXPLAIN THE ANSWER
NO. MASS IS THE AMOUNT OF MATTER IN AN OBJECT. WEIGHT IS GRAVITY PULLING ON MASS
WHAT IS A NORMAL FORCE
WHEN ONE FORCE PUSHES ON AN OBJECT AND THE OBJECT PUSHES BACK
WHAT FORCE ATTRACTS AND REPELS EACH OTHER WITH POSITIVE AND NEGATIVE ATOMS
ELECTRICAL FORCE
MAGNETIC FORCE
WHAT FORCE IS EXCERTED IN A TUG OF WAR GAME. ONLY ONE
TENSION FORCE
WHAT TYPE OF FORCES NEEDS TWO THINGS TO TOUCH
A CONTACT FORCE
WHAT TYPE OF FORCE DOES NOT NEED TWO OBJECTS TO TOUCH
NONCONTACT FORCE
