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?” in your own words

Answer:

Sample Response: If the starting height of a sloped racetrack is increased, then the speed at which a toy car travels along the track will increase because the toy car will have a greater acceleration.

Explanation:

The effect of the racetrack's height on the speed of the car is If the height of a sloped racetrack is increased, the speed at which a toy car travels along the track will increase due to greater acceleration.

How is speed related to height?

Height is directly proportional to the square of the velocity. If height is increased, then the final velocity of the moving object.

An example is When a ball is dropped from the top of a building, it accelerates as it falls. It accelerates by 10 m/s every second.

Thus, the  effect of the racetrack's height on the speed of the car is If the height of a sloped racetrack is increased, the speed at which a toy car travels along the track will increase due to greater acceleration.
