Force & Motion Take 3

Jonathan throws a football. A friend intercepts the pass by hitting it away from its intended target. hhat caused the change in the football's motion?

• The balanced force of the throw.
• The balanced force of the hit (interception.)
• The unbalanced force of the throw.
• The unbalanced force of the hit (interception.)

Monae predicts that if she pushes a marble down a ramp, it will go faster than if she just lets it roll down on its own. What should she measure to test this prediction?

• The height and length of the ramp
• The distance the car rolls in 5 seconds
• How much the car weighs after each roll
• How hard she can push the car in Newtons

Looking at the graph displayed, what is located on the x-axis?

• Bear population in Emerald Forest
• Years
• Population (in thousands)
• Numbers

Looking at the graph, what is located on the y-axis?

• Bear Population in Emerald Forest
• Years
• Population (in thousands)
• Numbers

Looking at the graph, what year held the highest population of bears?

• 2000
• 2003
• 2006
• There were no bears.

Looking at the graph, what happened to the population of bears between the years of 2004-2005?

• The population increased.
• The population decreased.
• The population remained constant.
• The population doubled.

Looking at the graph, which set of data is DEPENDENT on the other?

• The population of bears is dependent on the year.
• The year is dependent on the population.

Looking at the graph, between what years was there the greatest growth in bear population?

• 2000-2002
• 2001-2003
• 2003-2005
• 2005-2006

Explain what happened between the years 2004-2005. Why the flat line?

• The bear population died off in the years 2004-2005 so it flat-lined.
• The bear population decreased so the line is flat on the graph.
• There was no growth, nor decrease, so only time moves forward.
• The bear population increased so much that it flattened out the graph during those years.

The graph pictured shows the time it took Omar to slide across the different surfaces in his socks. Which surface did he slide on the fastest and why?

• He slid the fastest on Surface A because the bar graph illustrates a short amount of time.
• He slid the fastest on Surface B because the bar graph illustrates a short amount of time.
• He slid the fastest on Surface C because the bar graph illustrates a short amount of time.
• He slid fast on all three surfaces.
