Brian's lab group wants to know how friction affects motion. They designed an experiment to test the effect of different surfaces on the speed of an object. They covered a wooden block with different materials and then slid the block down a ramp and recorded its speed.
They ran the test 3 different times. Each time, they covered the block with a different material: felt, paper, and foil. The type of material used to cover the block is the -
Constant
Hypothesis
Dependent variable
Independent variable
Independent variable
