Student 1: RocketYwill have a smaller maximum vertical displacement than rocketX, although it is launched upward with the same speed as rocketXand has more kinetic energy than rocketX. Experiment 1 The students designed an apparatus that measures the rate of water absorption. A well-designed and conducted experiment should be able to be, Controlling events or conditions surrounding an experiment is very important for a well-designed experiment. Object C has an acceleration that is greater than the acceleration for D The problem here is that only one category of the population is considered.
