200
A CHANGE IN A MOVING OBJECT'S SPEED OR DIRECTION.
WHAT IS ACCELERATION?
200
THE LAW OF UNIVERSAL GRAVITATION SAYS THAT GRAVITATIONAL FORCE IS THIS. 
WHAT IS RELATED TO MASS AND DISTANCE?
200

200
MASS IS MEASURED IN THIS UNIT.
WHAT IS GRAMS OR KILOGRAMS?
200
DIVIDING THE TOTAL DISTANCE TRAVELED BY THE TOTAL TIME IS HOW TO CALCULATE THIS. 
WHAT IS AVERAGE SPEED?
300
A FORCE THAT ALWAYS ACTS TO OPPOSE MOTION.
WHAT IS FRICTION?
300
IF FORCES ARE BALANCE, THEN OBJECTS WON'T DO THIS. 
WHAT IS MOVE?
300
FRICTION OCCURS BECAUSE OF THIS.
