Students in a physics class were given several objects and asked to explore the nature of objects falling. The students drop each object from a height of 1.5 m. They use a timer to determine how long it takes each object to hit the ground. One of the students forgets to record the data for the time it took the samples of paper to fall. Their results are presented in the table as shown. Object Mass (kg) Time to Fall (s) balled-up a sheet of notebook paper 0.005 ? a flat sheet of notebook paper 0.005 ? physics book 5.0 0.55 Which answer is MOST LIKELY to approximate the results the students observed in their experiment? Answer A The balled up and flat sheets of paper both fell faster than the physics book because they have less mass.
