the empty wagon and the force doubles. What is the wagon’s new acceleration?
6. What does Newton’s 2nd Law of Motion state? (Hint: think about the
relationship between mass and acceleration AND force and acceleration)
7. What is the difference between inversely proportional and directly
proportional?
9. Create your own acceleration, force, or mass story problem and solve for either
acceleration (m/s2), force (N), or mass (kg)

STATION 3: Pressure and Terminal Velocity
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.

of 63 m2. What pressure does it exert on the ground? (46 Pa)
2) A Japenese sumo wrestler weighs 1480 N and his bear feet cover an area of
0.35 m2. What pressure does he exert on the ground? (4228 Pa or about 2114
Pa on each foot)
3) A snowboarder exerts a pressure of 900 Pa on a snowboard with an area of
0.65m2.What is the weight of the snowboarder? (585 N)
4) Provide an example of something we learned that is inversly proportional
besides mass and acceleration.
5) Explain how Mr. Vader survived the bed of nails demonstrations using Unit 3
academic words.
