Title: Friction and Force

Research Question: Which object takes the most force to pull?

Hypothesis: If cork is tested then it should take more force to pull, because its quality of friction

If the weight is higher, then the force required increases, because of the amount of weight.

Conclusion: Yes, our hypothesis was correct, but there must be factors that might sway in the favor. for instance, one of our recordings was incorrect or could be incorrect. because i was the tester, i was supposed to test everything, but i accidentally let rana have a go, but she didn't know how hard to push or pull, so this could of been incorrect.

Variables:
Independent variable: Force
Dependent variable: Weight
Controlled variable: Materials
