A group of students gather for some fun during their summer break from school. Kendall and Jacoby have a water balloon fight during one of those “lazy” days of summer.

Marie, Gary, and Lois remember a video about work that their science teacher, Ms. Lewis, showed them before they left for vacation.



Marie says: “If Kendall throws a water balloon at Jacoby, there is no work being done. It’s just boys being boys.”



Gary says: “If Kendall throws a water balloon at Jacoby, there is work being done by Jacoby because he has to run.”



Lois says: “If Kendall throws a water balloon at Jacoby, there is work being done because Kendall had to exert a force that made the water balloon travel a certain distance to hit Jacoby.”
