Answer
The scalar quantity among the options is distance (B), as it only has magnitude and does not have direction, unlike acceleration, force, and weight which are vector quantities.
Step 2

Answer
Measure the height from which the cupcake cases are dropped.
Measure the time taken for the cupcake cases to fall.
Use the formula:
extaveragespeed=timedistance
to calculate the speed, where distance is the height measured.
Repeat the experiment with different numbers of cupcake cases in the stack to see how it affects the speed.
Plot a graph of the speed of fall against the number of cupcake cases dropped, using average values.
