• True

At recess, a group of students play a game in which they throw a tennis ball against a brick wall on their playground. One students says: “The faster the ball is thrown, the more energy it has.” They test this statement by using a pitching machine to throw the ball against the wall at different speeds. Then, they measure how far the ball bounces off the wall each time. The table shows the data they collect. How does this data support the statement “The faster the ball is thrown, the more energy it has?”

• How far the ball bounces is related to how fast it is thrown.
• How far the ball bounces is not related to how fast it is thrown.
• The ball bounces farther when it is thrown at slower speeds.
• The ball bounces the same distance no matter how fast it is thrown.

What claim could be made about the data from the previous question?

• The ball’s energy increases after it hits the wall.
• The ball’s energy is not affected by hitting the wall.
• The ball’s energy decreases after it hits the wall.
• There is not enough data to support a claim.
