Suggest a way that you and a friend could measure the acceleration due to gravity, using a tennis ball, stopwatch, meter stick, and tape:

1. the procedure you would use,
2. assume and assign some values for the measurements you would make (don’t forget your
units),
3. and calculate what the acceleration due to gravity would be using your assigned values.

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
