Grace is doing an experiment on forces. She is testing to see how mass affects how far a piece of elastic can be stretched.
four weights on elastic bands
What might a hypothesis for this experiment be?
What is the effect of mass on how far elastic can stretch?
If the mass is greater, then the elastic will stretch more.
Mass is better than volume.
If the acceleration is greater, then the elastic will stretch more.
The hypothesis for this experiment could be: "If the mass of an object attached to an elastic band is greater, then the elastic band will stretch more."
A possible hypothesis for this experiment could be:
"If the mass of an object is greater, then the elastic band will stretch more."
Please note that the other two statements mentioned do not directly address the relationship between mass and the stretching of the elastic band, so they may not be suitable hypotheses for this particular experiment.
