STATION 3: Terminal Velocity and Short Answer
HINT- Use :
Directions: For all math problems, show all steps of the GUESS
method. Answers are in italicized parenthesis. Some problems may
require an explanation, give a complete thought.
1. If two quantities are inversely proportional to each other, does that mean as
one increases the other increases also?
2. Provide an example of something we learned that is directly proportional.
Explain how you know.
3. If the mass of a block is tripled at the same time the net force on it is tripled,
how does the new acceleration compare to the original acceleration?
4. If the force of a block is tripled at the same time the net force on it is tripled,
how does the new acceleration compare to the original acceleration?
