in an investigation, a student attaches one end of a spring scale to a 2 - kilogram block. the block is initially at rest on the level surface of a desk as shown. the student pulls on the other end of the spring scale. the student observes that a minimum force of 10 newtons is needed to start the block moving along the surface. the student repeats the procedure with a 1 - kilogram block and a 4 - kilogram block. the blocks are all made of the same material and the procedure is repeated on the same surface. use the menus to complete the statement about the variables in the investigation. in this investigation, the independent variable is the. the dependent variable is the
Answer
# Brief Explanations:
The independent variable is what the experimenter changes. Here, the student changes the mass of the block. The dependent variable is what is affected by the change in the independent variable. The minimum force needed to start the block moving changes with the mass of the block.
# Answer:
Independent variable: Mass of the block
Dependent variable: Minimum force needed to start the block moving
