Unit 2: Acceleration, Graphs and (finally?!) Formulas

Task 1:   You need to form groups of 3 to 4.   This will be your team for the unit.   In this group, you will assign roles:

• the planner/clearnup organizer
• the techie dude
• the setup person
• the paperwork person

Task 2:  Logger Pro and the world of motion.   Use a ramp and a cart to create a series of d-t and v-t graphs.  For each, you need to print the screen (one copy PER group), and then highlight 4 evenly-spaced time points on the v-t and d-t graphs.  For these, you will note the individual distances, velocities and times using the data chart to the right.   The setups include:

• a motion detector  at the top of a ramp, and a cart traveling down
• a motion detector at the bottom of a ramp and a cart traveling towards (but not hitting) the motion detector
• a motion detector attached to the ceiling and someone creating a vertical jump by standing, crouching, jumping, and then standing again
• a motion detector that is at the top of a ramp and a cart that is pushed up from the bottom, and then allowed to fall again.

Task 3:   Edible Race Cars.   Each member of your group must construct an entirely edible race car (except for 2 bamboo skewers, which may be used in any way desired).   The car will travel down a a ramp that has a motion detector at the top and must travel for 1 m.  Create a side view video of what is happening for each person using the Flip.

Task 4:   Copy the motion formulas on a notecard to be placed into your calculator or binder.    You must complete Worksheet 4 individually using both graphs AND formulas.

d = v(i)t + 1/2at^2
d = t * [v(i) + v(f)] /2 

v(f) = v(i) + at

v(f)^2 = v(i)^2 + 2ad
