Question

formulating a hypothesis
write a hypothesis about the effect of the racetrack’s height on the speed of the car using the format of \if… then…because…\. be sure to answer the lesson question \how can motion be described?\

Explanation:

A hypothesis is an educated guess. In this case, we consider the relationship between racetrack height (independent variable) and car speed (dependent variable). Motion can be described in terms of speed, which is related to the transfer of potential energy (from height) to kinetic energy (related to speed).

Answer:

If the racetrack's height is increased, then the speed of the car will increase because a higher racetrack gives the car more potential energy which is converted to more kinetic energy (and thus higher speed), and motion can be described by parameters like speed which is affected by energy changes related to the racetrack's height.
