A diagram of a student on a swing is shown.

Which statement correctly describes the forces that affect the student's position and motion?

• The force of gravity causes the student to speed up from Position A to Position B.

• The force of gravity causes the student to speed up from Position B to Position C.

• The force of the student's legs moving causes the motion to stop at Position B.

• The force of the student pulling on the swing causes the motion to stop at Position A.

Students conduct an investigation using a balloon rocket. They attach a balloon to a straw, connected to a string. They blow up the balloon rocket and let it travel along the string with and without a quarter as shown. How did adding the quarter MOST LIKELY affect the balloon?

• Force needed to move the balloon increased when the quarter was added. This is supported by the data because it took a longer time to move the balloon the same distance.

  
  

• Force needed to move the balloon decreased when the quarter was added. This is supported by the data because it took a shorter time to move the balloon the same distance.

Marta designed an experiment to test the effect of force on an object. In the illustration, she is holding the spring scale still.

What force is she measuring with the spring scale?

• the pull of the string

• gravity on the truck

• how hard she can pull

• friction on the truck's wheels
