Check if students can correctly predict that the ratio of the mass of the car to a persons mass would be the ratio of work done and energy gained (for example, if the cars mass was 10 times a persons mass, the amount of work needed to move the car to the top of the hill would be 10 times the work needed to walk up the hill). For example, if we want to determine the fraction of molecules that have velocities between 500 and 1000 m/sec, we need to measure the area of the shaded region below.
