# EL01 phone test: YOUR predictions, written and saved BEFORE you record any data.
# check.py compares this file's timestamp with your data file's and reports which came first.
# Replace every "?" with a number and a unit (or a word where asked), then save.
# Section 2.6 of EL01 has the physics; section 3.8 the procedure.

[lift]
# You lift it smoothly by about 30 cm, taking about a second, and hold it still.
