Variables:
Independent The mass of a muffin cup, grams [g], m
Dependent
The time it takes for the muffin cup to reach the floor, seconds [s], t
Controlled
Air resistance, Newton [N], FA Distance of releasing the muffin cup, meters [m], d Reaction time, seconds [s], t
Method for controlling variables: Air resistance will be controlled by having the same shape of the muffin cup for all tests. If this variable would not be controlled the time taken for the muffin cup to reach the floor would be affected dependent on the shape differences. The distance of releasing the muffin cup will be controlled by releasing the muffin cup from the
