One of the laws of motion states, "An object in motion stays in motion unless an unbalanced force acts upon it." On Earth, objects always seem to eventually come to a stop when more force is not being applied. What force is causing the objects to eventually stop moving?

• Mass

• Friction

• Weight

• Gravity

According to the above information and diagram, what will be the result?

• The box will move to the right with 8 N force.

• The box will move to the right with a 24 N force.

• The box move to the left with a 2 N force.

• The box will move to the left with 8 N force.

Free-body diagrams for four situations are shown below. For each situation, determine if the force is balanced or unbalanced. Start with the top and work your way down.

• unbalanced, balanced, balanced, balanced

• unbalanced, unbalanced, balanced, unbalanced

• balanced, unbalanced, unbalanced, balanced

• unbalanced, balanced, unbalanced, unbalanced

Use the free-body diagrams to answer the question. Which of the two diagrams has the same net force?

• Diagram A

• Diagram B

• Diagram C

• Diagram D
