A student designed an investigation to determine what affects motion caused by unbalanced forces. Shown is her experimental design.

Is her investigation a fair test?

• No, because she has two responding (dependent) variables.

• No, because she has two manipulated (independent) variables.

• Yes, because she uses distance as a controlled variable.

• Yes, because she uses time as the responding (dependent) variable.
