A group of 4 scientists attached a spring scale to a bottle full of water and used a spring scale to pull it 40 cm. They recorded the amount of force in Newtons needed to pull it in the data table below. Then they attached the same bottle with no water and pulled it 40 cm. They recorded the amount of force in Newtons needed to pull it in the data table. Which of the scientist's conclusions are correct about the experiment?

• Scientist 1 – It takes the same amount of force to move both water bottles.

• Scientist 2 – It takes more force to move less mass.

• Scientist 3 – It takes more force to move more mass.

• Scientist 4 – There is not enough information to make a conclusion.
