Students want to test gravity. They want to drop four objects with the same mass from the top of the bleachers they will time how long each object takes to reach the ground how can they improve confidence in their schools experiment
randomly slect the order in which the objects are dropped
let a differnt kid time the drop of each object
drop all four objects at once
drop each object 10 times and use the average of each fall times
