- 7. Multiple ChoiceNewton's third law states that any action will have a(n) _______ and ______ reactionEqual and similarEqual and oppositeEqual and differentGreater and opposite
- 8. Multiple Choice
A bowling ball strikes a pin. Which one accelerates more?
The bowling ball because it is more massive
The pin because it is more massive
The pin because it is less massive
They accelerate the same
- 9. Multiple ChoiceWhich best explains why we are able to accelerate forward when starting to run?As one leg moves backward, it provides an equal and opposite force for the other foot to move forward.No acceleration takes place. Runners are always at a fixed velocity.The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.The runner's upper body quickly leans forward, causing the entire body to begin accelerating forward
- 10. Multiple ChoiceWhen a cannon fires a cannonball we observe Newton's third law. Which force is the reaction force?The cannon moving forwardThe cannonball moving forwardThe cannon moving backwardThe cannonball moving backward
- 11. Multiple ChoiceA person steps out of the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward. Which statement best describes the backward motion of the boat as the person steps forward?For every action there is an equal and opposite reaction.Every mass exerts a force on every other mass.An object at rest tends to stay at rest.Friction opposes the motion of an object.
- 12. Multiple ChoiceWhat is Newton's First Law known as? The Law ofFrictionMassInertiaGravity
- 13. Multiple ChoiceWhat kind(s) of objects have inertia?all objects with massonly objects at restonly objects in motiononly objects whose motion is being changed
- 14. Multiple ChoiceWhich type of force(s) will cause a change in an object's motion?gravityzero net forcebalanced forcesunbalanced forces
- 15. Multiple ChoiceWhat is Newton's First LawF=maEvery action has an equal and opposite reactionAn object at rest stays at rest, an object in motion stays in motion.Friction
- 16. Multiple ChoiceOne object has twice as much mass as another object. The first object also has also twice as much...velocitygracitational accelerationinertiaall of these
- 17. Multiple ChoiceWhat is inertia?the force that opposes motionthe force of attraction between 2 objectsan object's tendency to stay in motion or to stay at resta change in an object's speed and/or direction
- 18. Multiple ChoiceAccording to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force willremain in motion.eventually come to a stop.change its momentum.accelerate.
- 19. Multiple ChoiceWhy does an 18-wheeler have more inertia than a bicycle?it has more massit has more volumeit is not as aerodynamic
- 20. Multiple ChoiceThe inertia of an object depends on itsmassspeedvelocitydirection
