Question

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?”

Answer 1

If the racetrack's height is increased, then the speed of the car will decrease, because an increase in height will result in an increase in gravitational potential energy. As the car moves uphill on a higher track, it will gain more potential energy and consequently lose kinetic energy, leading to a decrease in speed. This hypothesis is relevant to the lesson question as it explains how changes in the track's height can affect the motion of the car.
