Question

What are the two variables? Explains

Answer 1

Answer: Type of paper and force of throw.

Explanation:

Depending on the type of paper, the weight may change which will affect the throw. For the reason he is testing the shape affecting the flight, and not the weight, the paper would have to be the same kind. The force of the throw could also affect the distance, so that would also have to stay the same in order to be properly tested.
