The Prezi was very well done. It looks like there were errors in your second data set. It would be easier to see if there were a data table included. You must always present the data you collected in a table, then graph it. Your conclusion is correct but it is really not supported by the data. You need to defend your conclusion by developing it from the data. 26/30 media type="custom" key="11501610"

Well done, Kelsey. It would have been good to include a general statement in your conclusion that could apply to all objects such as ...an object of greater mass will experience a greater net force but its mass is proportionately greater. Since acceleration is directly proportional to force and inversely proportional to mass, an object of greater mass and an object of lesser mass will accelerate at the same rate and under these conditions will hit the ground at the same time. +10
