Fifth Grade Benchmark Assessment Force/Motion/Machines 1. A small steel ball bearing and a large glass marble were dropped from the same height at the same instant. Which would happen? A. B. C. D. They would hit the floor at the same time. The steel ball bearing would hit first because it is smaller. The glass marble would hit first because it is larger. The steel ball bearing would hit first because it is heavier. Use the chart below to answer question 2. 2. A racecar completes its laps as shown. The chart indicates that the car is A. B. C. D. accelerating increasing inertia maintaining its velocity increasing its potential energy Use the picture below to answer question 3. 3. Anne is testing toy carts by seeing how fast they are rolling when they reach the end of a ramp she built. How can she change the investigation so the carts will be going faster when they reach the end? A. B. C. D. Add carpet to the surface of the ramp. Start the cars further down the ramp. Raise the angle of the ramp. Take some weight off of the carts. 4. Which type of force causes a moving train to come to a stop? 5th – Force/Motion/Machines - -1- A. B. C. D. gravitational frictional magnetic chemical 5. The force that keeps a communications satellite in orbit around Earth is A. B. C. D. gravity friction magnetism electricity Use the picture below to answer question 6. 6. Harry was standing. Now he is running. When he is running he has more A. B. C. D. potential energy kinetic energy mass gravity 7. What force pulls things toward the center of Earth? A. B. C. D. friction gravity magnetism electricity 8. Objects in an orbiting space shuttle float because A. B. C. D. the space shuttle slows down when it reaches orbit Earth’s gravity has less effect on objects as they get farther away from Earth. the weight of the object is less when orbiting the Earth the space shuttle’s engines cause too much vibration for objects to remain still 9. The Sun’s gravity holds each planet in its orbit. Pluto is farther away from the Sun than Earth is. How does the effect of the Sun’s gravity on Pluto compare with the effect of the Sun’s gravity on Earth? 5th – Force/Motion/Machines - -2- A. B. C. D. The Sun has the same gravitational pull on all planets that are in orbit. The Sun has more gravitational pull on Pluto because it is smaller. The Sun has less gravitational pull on Earth because it is closer. The Sun has less gravitational pull on Pluto because it is farther away. 10. The school bus is moving at 55 miles per hour. Before it can go 60 miles per hour, A. B. C. D. an additional force must act on the bus the bus must have more inertia a physical change must happen there must be less air resistance 11. Suppose that you want to drop a penny and a quarter at exactly the same time and have them hit the floor at exactly the same time. Which picture BEST shows how you should hold the penny (P) and the quarter (Q) just before you drop them? A. B. C. D. 12. Which of the following BEST describes “distance”? 5th – Force/Motion/Machines - -3- A. B. C. D. a large, flat space how long it takes for something to happen a long way to go how far it is between two points 13. A swimmer is able to swim at a rate of 75 meters per minute. How long would it take the swimmer to complete a 1500-meter race? A. B. C. D. 20 minutes 75 minutes 112 minutes 1425 minutes 14. While riding in the backseat of a car, a child holds a cup of juice. When the car suddenly stops, the liquid in the cup will A. B. C. D. flow off to one side of the cup flow toward the back of the cup flow in the direction the car was moving stop as suddenly as the car stops 15. Which ball has the MOST potential energy? A. B. C. D. 16. A crumpled sheet of paper will fall to the ground faster than an uncrumpled sheet because crumpling the paper 5th – Force/Motion/Machines - -4- A. B. C. D. causes it to have less mass causes it to have less air resistance changes the chemical state of the paper adds potential energy 17. A roller-coaster car raced down a track going faster and faster as it neared the bottom of a hill. What term describes this increase in speed? A. B. C. D. inertia velocity potential energy acceleration Use the picture below to answer question 18. 18. If the horse rider is traveling at a rate of 1 km every four minutes and the cattle are traveling at a rate of 1 km every 12 minutes, will the rider meet the cattle at the point labeled “X” ? A. B. C. D. No, the rider will arrive 4 minutes after the cattle pass point “X” No the rider will arrive 8 minutes after the cattle pass point “X” Yes the rider and the cattle will arrive at point “X” in 12 minutes Yes, the rider and the cattle will arrive at point “X” in 4 minutes 19. A car traveling from Jesup to Macon has an average velocity of 45 miles per hour. The distance between these two cities is 149 miles. Approximately how long will it take the car to complete the trip?
