Newton's Laws of Motion

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

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

• 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

• 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

The risk of injury in a car accident is much greater if occupants do not wear a seat belt. Which of Newton's laws explain why this is true?

• Law of force and acceleration

• Law of gravity

• Law of action and reaction

• Law of inertia

What is Newton's Third Law?

• Object in motion stays in motion and an object at rest stays at rest unless acted on by a outside force
• Force = mass x acceleration
• For every action there is an equal and opposite reaction
