Worked Solution & Example Answer:5. (a) Which of these is a scalar quantity? A - Edexcel - GCSE Physics Combined Science - Question 5 - 2023 - Paper 1
Step 1
Step 2
A student has some cupcake cases.
Answer
-
Measure the height of one cupcake case using a ruler.
-
Measure the time of fall for the stack of cupcake cases with a stopwatch.
-
Use the formula for speed: speed = distance/time. In this case, distance refers to the height measured in step 1.
-
Repeat the experiment with different numbers of cupcake cases in the stack and record the time taken to fall.
-
Calculate the average time for each stack size, and determine the average speed for the cupcake cases.
-
Plot a graph of speed (on the y-axis) against the number of cupcake cases dropped (on the x-axis).
