four weights on elastic bands it can stretch from 20g to 50g

Which is a problem question for this experiment?

Mass is better than volume.

What is the effect of mass on how far elastic can stretch?

If the mass is greater, then the elastic will stretch more.

If the acceleration is greater, then the elastic will stretch more.

What is the effect of adding more weight to the elastic bands on how far they can stretch?

Grace is doing an experiment on forces. She is testing to see how mass affects how far a piece of elastic can be stretched. The elastic bands can stretch to 20g to 50g
