- 1. Multiple Choice
Two objects are connected by a rope over a pulley. According to Newton's Second Law of Motion, the masses will start to move if theacceleration of object 1 is greater than acceleration of object 2acceleration of object 2 is greater than acceleration of object 1mass of object 1 is greater than the mass of object 2mass object 2 is greater than the mass of object 1 - 2. Multiple ChoiceWhich statement best explains Newton's Third Law of Motion?An object at rest tends to stay at rest.For every action there is an equal and opposite reaction.The acceleration of an object is based on the force applied.An object continues its motion until an unbalanced force is applied.
- 3. Multiple ChoiceWhich is the best example of Newton's First Law of Motion?a basketball thrown in the air falls to the grounda soccer ball remains motionless until it is kicked by a playera baseball player swings at an approaching ballan ice skater pushes back from a wall and moves backwards
- 4. Multiple ChoiceAn object is resting motionless on a surface. According to Newton's 1st Law, the object will only start to move ifthe net forces on the object equal zeroan unbalanced force is applied to the objectthe upward force of the object is equal to its accelerationtwo forces that are equal and opposite are applied to the object
- 5. Multiple ChoiceAs the wheels of a train push down on the track, the track pushes back against the wheels. Which of Newton's laws is used to explain these forces.An object at rest tends to stay at rest unless acted upon by an unbalanced force.The net force of an object is its mass times its acceleration.For every action, there is an equal and opposite reaction.Any 2 objects exert a gravitational force of attraction on each other.
- 6. Multiple ChoiceWhich example best explains Newton's Third Law of Motion?When a glass slid across a table, it spilled water when it stopped suddenly.An engine used less work to move a lighter car than when it moved a heavier car.When you sit on a chair, your body exerts a downward force on the surface of the chair, while the chair exerts an equal and upward force on your body.
- 7. Multiple ChoiceA truck that is travelling at a constant speed is carrying some boxes. If the truck comes to a sudden stop, what will most likely happen to the boxes?They will stay in the middle of the truck.They will slide toward the front of the truck.They will slide toward the back of the truck.They will fall off the side of the truck.
- 8. Multiple ChoiceA student throws a ball against a wall. Which statement best explains what is happening in the picture.The energy of the ball is destroyed as it strikes the wall.The energy of the ball becomes negative as it hits the wall.The force from the wall on the ball is equal and opposite to the force from the ball on the wall.The force exerted by the ball on the wall is greater than the force exerted by the wall on the ball.
- 9. Multiple ChoiceObject X has twice the mass of Object Y. Both objects are accelerating at the same rate. Which statement best describes the motions of Object X and Object Y.Object X is travelling at twice the speed as Object Y.Object X is travelling at half the speed as Object Y.Object X requires twice the force to accelerate at the same rate as Object Y.Object X requires half the force to accelerate at the same rate as Object Y.
- 10. 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.
- 11. Multiple ChoiceThe force that draws all objects towards Earth.frictiongravitymassacceleration
- 12. Multiple ChoiceA rubbing together force that slows things down and stops them. It works against motion.accelerationmassgravityfriction
- 13. Multiple ChoiceWho invented the 3 Laws of Motion?Sir Francis BaconSir Isaac NewtonJohannes KeplerGalileo Galilei
- 14. Multiple ChoiceIf you are shooting a basketball, the basketball pushes on your hand as your hand pushes on the basketball. This is Newton's 3rd law of motion that saysfor every action there is an equal and opposite reactionan object at rest will stay at rest unless acted on by an unbalanced forceacceleration is produced when a force acts on a mass, the greater the mass, the greater the amount of force needed to accelerate the objectan object in motion will remain in motion unless acted on by an unbalanced forece
- 15. Multiple ChoiceWhen did Isaac Newton first become interested in forces and motion?at birthin his old agein collegewhen he met Mrs. Carter
- 16. Multiple ChoiceThe soccer ball is sitting on the half line and Zach runs up to kick it. What law will occur when he kicks it?An object at rest will remain at rest unless acted on by an unbalanced force.An object will remain motionless until it decides to move.The harder Zack kicks the ball, the less distance it will travel.Time travel has always been possible. You just have to believe.
