yes. All objects accelarate torwards the earth at 9.8 m/s2 So you could test a golf ball and drop it with a bowling ball or something similar. It takes longer for the larger object to accelarate, while the smaller object accelarates faster but doesnt accelarate much after that so the technically they are balanced in the air. But you cant test a peice of paper and a basevball because the peice of paper would have a larger surface area and more friction would slow it down longer. But yes that is a valid science project. G luck
