STAAR Test Force

In the picture above, two teams of students are playing tug-of-war. Each team is pulling in the opposite direction, but both teams are moving in the same direction. Which of the following best describes the forces in this situation? (8.6A)

• The forces are balanced and the net force is zero.

• The forces are balanced and Team A is exerting a greater force.

• The forces are unbalanced and Team A’s force is greater.

• The forces are unbalanced and Team B’s force is greater

A spring scale is a tool that measures the strength of force needed to move an object. The force is measured in Newtons (N). A student sets up two spring scales pulling wooden boxes of different masses across a table. Which question is the investigation most likely designed to answer?

• How does mass affect the force needed to move an object?

• How does the surface affect the force needed to move an object?

• How do wooden blocks affect spring scales?

• How does the mass of one block affect the mass of another block?
