- 1. Multiple ChoiceObjects in orbit around the earth (a satellite) still have net forces acting upon them.TrueFalse
- 2. Multiple ChoiceAn object's inertia causes it to come to a rest postition.TrueFalse
- 3. Multiple ChoiceYou and your friend are playing tug of war. What is the equal and opposite force to the force of your hand pulling the rope described with Newton's 3rd Law ?The force of your friend pulling on the rope in the opposite directionThe force of the rope pulling on your hand in the opposite directionThe force of your arm pulling back on your handThe force of friction between the ground and your shoes
- 4. Multiple ChoiceMass is a measure of an object's inertia (or its tendency to resist change in velocity).TrueFalse
- 5. Multiple ChoiceWeight and mass are the same thing.TrueFalse
- 6. Multiple ChoiceAn object that is not accelerating or decelerating has zero net force acting on it.TrueFalse
- 7. Multiple ChoiceAn object that is not accelerating or decelerating has no forces acting on it.TrueFalse
- 8. Multiple ChoiceA stationary object has no forces acting on it.TrueFalse
- 9. Multiple ChoiceWhat causes a runner to lean forward ?The striking foot pushes backward against the ground. The friction with the ground provides an equal and opposite force forward.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 runner's upper body quickly leans forward, causing the entire body to begin accelerating forward.
- 10. Multiple ChoiceA force that will work against motion in every situation is...FrictionGravityInertiaFall
- 11. Multiple ChoiceWhen a car suddenly stops, the objects in the back seat are thrown forward. This is due to __________.Law of gravitationLaw of force and accelerationLaw of InertiaLaw of action-reaction
- 12. Multiple ChoiceIf the object is NOT moving, where is the acceleration coming from to cause the force to increase as the mass increases?FrictionSpin of EarthGravityMovement around the sun
- 13. Multiple ChoiceForce = mass x __________.AccelerationSpeedVelocityDistance
- 14. Multiple ChoiceNewton's First Law is also called the __________ of __________.Law of action-reactionLaw of inertiaLaw of acceleration
- 15. Multiple ChoiceWhen you push a crate up a ramp the crate is __________ back on you.PullingPushingSpittingHitting
- 16. Multiple ChoiceThe more mass an object has the more __________ it will take to move the object from rest or stop the object once it is in motion.WeightMassInertiaForce
- 17. Multiple ChoiceFor every action force there is an __________ and opposite reaction force.EqualOppositeActionReaction
- 18. Multiple ChoiceFor every action force there is an equal and __________ reaction force.EqualReactionOppositeSame
- 19. Multiple ChoiceFor every action force there is an equal and opposite __________ force.ReactionSameEqualOpposite
- 20. Multiple ChoiceThe less __________ an object has the less force it will take to move the object from rest or stop the object once it is in motion.ForceMassStopWeight
