What is the purpose of making marks behind the center of the swing?

To determine the speed of the swing
To indicate the points of release for the swing (correct)
To measure the weight of the person in the swing
To measure the distance of the swing from the center

Why does the smallest person get to do the next experiment?

Because they are the smallest and can fit in the swing
Because it's a random selection process
Because they are the strongest
Because their weight will not affect the swing's motion (correct)

What is the purpose of having two people pull the swing back to the first mark?

To measure the distance of the swing
To slow down the swing's motion
To add extra force to the swing's motion
To release the swing at a consistent starting point (correct)
