Formative #2 Test #3 Force and Newton

A truck is towing a trailer straight with 700 Newton's of force. Which of the following statements is NOT true?

• The net force is zero.

• The truck is running into 700 Newton's of friction.

• The truck is accelerating.

• This is a good example of Newton 1 and Newton 3.

Which of the following is NOT true about friction?

• It occurs any time two objects are in contact

• It always acts in the opposite direction as motion

• It always acts in the same direction as motion

• It prevents objects on earth from staying in motion forever

• 12 N Right  No
• 4 N Left  No
• 12 N Right  Yes
