In which section of the lab report would the reader find the steps to recreate the experiment?

• Hypothesis

• Variables

• Procedure

• Analysis

What can you infer about the experiment results if the angle was increased more each time?

• The time will keep on shortening.

• The time will increase.

• The car will be damaged.

• It will be difficult to measure.

Which of the following best describes how the text was structured?

• Descriptive

• Process

• Compare and Contrast

What is the main idea of the selection?

• The hypothesis can be further experimented by looking at other forces involved in the movement of the car such as friction.

• Based on the data, the force of gravity is highest at the steepest angle because that is when the car travels the fastest.

• When the ramp was angled at 80º the car traveled the fastest.

• A bar graph is the best way to display the data from this experiment.
