Revolt · Accepted Answer

✔ height of the track; In this experiment, the was intentionally manipulated. This was the independent variable.: height of the track; The dependent variable measured was the .: speed of the car

Question 2

✔ speed of the carheight of the trackdistance traveled

Revolt · Accepted Answer

✔ speed of the car

Question 3

Revolt · Accepted Answer

0.13

Question 4

Use the table to answer the questions.

Revolt · Accepted Answer

2.02; 2.15; 0.13

Question 5

Match the measurement with the proper SI unit.

Revolt · Accepted Answer

✔ Meters per second squared; Acceleration:: Meters per second squared; Velocity:: Meters per second; Distance:: Meters

Question 6

Calculate speeds for each track. How much faster was the car on the higher track than the lower track?

Revolt · Accepted Answer

✔ Cars travel faster on the higher track.; Based on the time measurements in the table, what can be said about the speed of the car on the lower track as compared to the higher track?: Cars travel faster on the higher track.; How can the reasoning for the above answer be best explained? On the higher track, the elapsed time is .: shorter; 0.56 m/s

Question 7

Read the elapsed time on the stopwatch and answer the questions.

Revolt · Accepted Answer

7; 4

Question 8

Use the graph of distance versus time to complete the sentences.

Revolt · Accepted Answer

✔ farther than; The cars on the higher track travel the cars on the lower track, in the same time.: farther than; This means that the cars on the higher track have a average speed than those on the lower track.: greater; This is demonstrated by the of the higher track line being greater than the slope of the lower track line.: slope

Question 9

Use the graph of speed versus time to answer the questions about acceleration.

Revolt · Accepted Answer

A; C; B
