Gather all of your equipment‚ a LabQuest 2‚ two friction blocks (one with sandpaper and one with foam)‚ a force sensor‚ slotted masses‚ a ruler‚ and two sheets of graph paper. Weigh the two friction blocks in kilograms. Then multiply that number by g‚ 9.8‚ to find the blocks’ weights in Newtons and record it. Plug the force sensor into channel 1 of your LabQuest 2‚ this allows you to calculate the amount of force that you pull the block with. Choose six of the slotted masses to place on the blocks
