A student inflates a balloon attached to a plastic straw. A string is threaded through the straw and tied to opposite ends of the room. When the air in the balloon is released, the balloon travels the length of the string. Which of Newton's laws explain this?

• The law of action-reaction

• Newton's law of magnetism

• The law of force and acceleration

• The law of gravity

A car driving down the road runs out of gas. Which of Newton's laws explains why the car continues to move without gasoline? Be able to explain why. This will be a constructed response question.

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

Which of the following would be a good example of Newton's third law of motion?

• An air freshener hanging from the rear-view mirror of a car hangs still while the car moves forward with a constant acceleration

• A carbon dioxide-fueled rocket launches upward into the air as carbon dioxide gas accelerates toward the ground below the rocket

• Two balls of different masses are rolled with the same force, resulting in the ball with larger mass stopping faster than the ball with the smaller mass.

• All of the above

Match the following Law of motion with the correct example

• Bouncing the ball on the court is the action, the floor pushing the ball back up is the reaction

• Newton's 1st law of motion

• Hit a ball with 2 different forces, the ball will have greater acceleration due to larger force

• Newton's 3rd of motion

• Roll a ball across smooth/rough surfaces. The ball rolls faster on smooth because less fiction

• Newton's 2nd law of motion
