the effect of paper thickness on the distance covered by a paper plane. Hypothesis The thinner the paper the further the paper plane would glide so it would cover a larger distance. This is because of the smaller gravity force acting on the paper plane made out of the thinner paper‚ since the mass of this plane is smaller. Apparatus Tape measurer Blue tack 6 sheets of different types of paper (office paper‚ paper towel‚ cardboard of different thickness and recycled paper) Method 1
