Students set up an experiment in which a block is given an initial push on a rough horizontal surface, and the block slides through a photogate. the photogate is used to determine the block’s speed, and the students use a meter stick to measure the distance that the block slides past the photogate before coming to rest. the students repeat the experiment for several trials. for each trial, the block is given a different speed through the photogate. is a scientific hypothesis that can been tested by the data collected by the students.
