Hypothesis:​​ ​As​ ​the​ ​weight​ ​of​ ​washers​ ​increases,​ ​speed​ ​and​ ​acceleration​ ​will​ ​increase​ ​to​ ​keep the​ ​radius​ ​up​ ​at​ ​1​ ​meter. Materials:​​ ​rubber​ ​stopper,​ ​string​ ​over​ ​a​ ​meter​ ​long​ ​with​ ​a​ ​tube​ ​over​ ​it,​ ​alligator​ ​clip,​ ​paper​ ​clip, washers,​ ​timer Procedure: 1. Mass​ ​the​ ​rubber​ ​stopper,​ ​alligator​ ​clip,​ ​and​ ​paper​ ​clip,​ ​and​ ​record​ ​the​ ​data. 2. On​ ​one​ ​end​ ​of​ ​the​ ​string,​ ​tie​ ​the​ ​rubber​ ​stopper,​ ​and​ ​on​ ​the​ ​other​ ​end,​ ​tie​ ​the​ ​paper​ ​clip. 3. Measure​ ​a​ ​meter​ ​of​ ​string​ ​from​ ​the​ ​stopper​ ​and​ ​mark​ ​it​ ​with​ ​an​ ​alligator​ ​clip. 4. Find​ ​and​ ​record​ ​the​ ​mass​ ​of​ ​10​ ​washers,​ ​and​ ​attach​ ​them​ ​to​ ​the​ ​paper​ ​clip. 5. Holding​ ​the​ ​tube​ ​on​ ​the​ ​string,​ ​spin​ ​the​ ​rubber​ ​stopper​ ​above​ ​you​ ​in​ ​a​ ​circle,​ ​and​ ​when the​ ​tube​ ​reaches​ ​the​ ​alligator​ ​clip​ ​(so​ ​it​ ​has​ ​a​ ​1​ ​meter​ ​radius),​ ​record​ ​the​ ​time​ ​it​ ​takes​ ​to go​ ​10​ ​revolutions.​ ​ ​Make​ ​sure​ ​to​ ​keep​ ​the​ ​radius​ ​at​ ​1​ ​meter​ ​the​ ​whole​ ​time. 6. Repeat​ ​step​ ​5​ ​with​ ​an​ ​additional​ ​5​ ​washers​ ​added​ ​to​ ​the​ ​paper​ ​clip,​ ​and​ ​add​ ​their​ ​mass to​ ​the​ ​recorded​ ​mass​ ​of​ ​the​ ​existent​ ​washers. 7. Repeat​ ​steps​ ​5​ ​and​ ​6​ ​until​ ​you​ ​have​ ​data​ ​for​ ​20,​ ​25,​ ​30,​ ​35,​ ​40,​ ​45,​ ​and​ ​50​ ​washers.
