2. Which Law of Motion is being demonstrated in this picture? a) Equal and Opposite forces b) F=ma c) Increasing the mass increases the force needed to accelerate an object.

3. Which law of motion is being illustrated? a) Equal and opposite forces. b) Increasing the mass increases the force needed to accelerate an object c) An object in motion remains in motion until acted on by an outside force.

4. Which law is represented? a) Equal and opposite forces b) For every action there is an equal and opposite reaction c) For every push there is a pull d) All of the above

5. Which one of Newton’s Laws is being demonstrated in this picture? a) Equal and opposite forces b) Unbalanced forces c) Increasing the mass increases the force needed to accelerate an object.

7. An astronaut with a tool belt accidentally pushed off from the shuttle and could not get back to the shuttle. He threw his tools, one at a time, away from the shuttle. Eventually, he was able to return to the shuttle after throwing all of his tools from his tool belt. Which of Newton’s laws was used in this scenario to get the astronaut back to the shuttle? a)Force of gravity and acceleration b)For every action force, there is an equal and opposite reaction force. c)F=ma d)An object in motion stays in motion unless acted on by another force.

8.A dump truck moves more slowly when it is filled with a load. Which law of motion applies? a)Force=Mass X Acceleration b)Increasing the mass increases the force needed to accelerate an object. c)An object in motion remains in motion until acted on by an outside force d)Both a and b e)Only a.

9. Which one of Newton’s laws would you use to determine which object would be easier to move? a)For every action there is an equal and opposite reaction b)An object at rest tends to stay at rest unless another force is applied on the object c)F=mXa

10. Which law is this demonstrating? a)Equal and opposite forces b) The more mass an object has, the harder it is to accelerate. c) Friction d) None of the above

11. Looking at the same picture, which person has more inertia? a) the larger wrestler b) the smaller wrestler c) both have the same Inertia d) none of the these

12. If you were to slide these books across a table, one by one, the books would eventually stop their motion. What force or forces are the cause of the books stopping their motion? a)Centrifugal force b)Friction and gravity c)Centripetal force and Centrifugal force d) Just gravity 13. Which of Newton’s laws is being demonstrated ? a)Equal and opposite forces b)Force = mass X acceleration c)An object in motion stays in motion unless and outside force acts upon it. An object at rest remains at rest unless an outside force acts upon it.

14. Fuel burning in this rocket’s combustion chamber creates gases. The rocket exerts a force on these gases to expel them out of the nozzle at the bottom of the rocket. As a result, there is an upward force exerted on the rocket by the gases. Which of Newton’s laws is being used in this example? a) For every action, there is an equal and opposite reaction. b) An object at rest stays at rest unless another force is applied. c) The more mass an object has, the harder it is to accelerate.
