Question

speed - velocity - acceleration inquiry lab
conclusion: how does the steepness of a ramp affect the speed of a car?
claim: when the ramp is steeper, the speed of the car _.
evidence: when the ramp was one textbook high, it took an average of seconds to reach 1.0 meters. when the ramp was two textbooks high, it took an average of seconds to reach 1.0 meters.
reasoning: the results show that when the ramp is _, the car travels the same distance in less time. since _ is the measure of how fast something travels, this means the _ increased for the _ ramp.

Explanation:

The claim is about the relationship between ramp steepness and car speed. Evidence would be specific times (though actual values not given here). Reasoning connects steeper ramp (less time for same distance) to speed (measure of how fast) increasing for steeper ramp.

Answer:

Claim: When the ramp is steeper, the speed of the car \( \text{increases} \).
Reasoning: The results show that when the ramp is \( \text{steeper} \), the car travels the same distance in less time. Since \( \text{speed} \) is the measure of how fast something travels, this means the \( \text{speed} \) increased for the \( \text{steeper} \) ramp.
