You and 3 of your friends are having a contest to see who can throw a ball the fastest. You learned in science class that the more force you use, the faster the ball will go. You each throw a ball and time the ball to how long it takes to get from one person to another. How do you know who threw the ball with the most force?

• The person with the lowest time used the most force

• The person with the highest time used the most force

• There is no way to tell who used the most force
