Investigating Force Passage

Which of the following is the best definition of gravity?

• The force that pushes objects down

• The force that pulls objects together

• One object colliding into another

• The force that causes objects to speed up

In the hypothesis, what does the word steepest mean?

• Largest

• Smallest

• Having the most vertical slope

• Having the flattest slope

What is a protractor used to measure?

• Time

• Length

• Distance

• Angle

How many variables were tested during this experiment?

• One

• Two

• Eight

• None

What type of graph is used to display the experiment's results?

• Line graph

• Pie chart

• Bar graph

• Pictograph

Which of the following are true statements about the experiment? (Select all that apply.)

• The experiment tested more than one variable.

• The writer’s hypothesis was correct.

• The force of friction was tested in the experiment.

• The car’s time down the ramp was the dependent variable.

• The steepest angle that was tested was 80º.

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 only increased by 5º each time?

• The car’s time down the ramp would increase as the ramp’s angle was increased.

• The data would trend in the same way it did at 10º.

• The experiment is not possible if the angle is increased 5º each time.

• The dependent and independent variables would switch.

Which of the following best describes the text structure of the selection?

• Process

• Compare and contrast

• Descriptive

• Chronological

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.
