object. Bo wants to use this law to predict how a soccer ball will
roll on the grass after he kicks it. Which statement best describes

and the grass makes it stop.

Question 3 - 30
• Mackenzie investigates how the volume of gas inside a balloon
changes as the temperature of the gas changes. She takes an inflated,
sealed balloon from a freezer and uses a string and a meterstick to
measure the balloon’s circumference. She moves it to a sunny
window for 15 minutes. Then, she measures the circumference with a
tape measure. She records these measurements in a data table.
