Question

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.

Answer 1

Answer:

The correct answer is theory.

Explanation:

A theory is a scientific postulate that can be proved through experiments and the data that comes from them. Nevertheless, theories are always open and susceptible for change, because they are not an absolute truth and further experiments can lead to different conclusions.
