Force and Motion Test

What is Newton's First Law of Motion?

• Every action has an equal and opposit reaction

• Objects in motion stay in motion/Objects at rest stay at rest until an outside force acts on it

• A force is required to accelerate an object with a known mass

What is Newton's Second Law of Motion?

• Every action has an equal and opposite reaction

• Objects in motion stay in motion/objects at rest stay at rest until an outside force acts on it

• A force is required to accelerate an object with a known mass

What is Newton's Third Law of Motion?

• Every action has an equal and opposite reaction

• Objects in motion stay in motion/objects at rest stay at rest until an outside force acts on it

• A force is required to accelerate an object with a known mass

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

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

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
