  1. Physic Final Review Velocity, Acceleration & Projectile Motion

  2. Which graph best represents a positive acceleration? • [IMAGE] • [IMAGE] • [IMAGE] • [IMAGE] 1. 2. 3. 4. 10

  3. Students studied a graph of the motion of a toy car.What is the acceleration of the toy car in the time interval between 15 and 20 seconds? • [IMAGE] • [IMAGE] • [IMAGE] • [IMAGE] 1. 2. 3. 4. 10

  4. The graph shows the velocity of two different cars during a period of ten seconds. During which time interval is the acceleration of Car 1 equal to zero relative to Car 2. • 2 to 3 seconds • 4 to 5 seconds • 5 to 6 seconds • 9 to 10 seconds

  5. The graph shows the velocity of a vehicle recorded during a 4 hour time. Which part of the graph shows the greatest acceleration rate? • 1 • 2 • 3 • 4

  6. Diana hangs a lead cylinder with a force of 12 N from a model bridge.Which vector(s) accurately illustrate the reaction force of the bridge on the lead cylinder? • [IMAGE] • [IMAGE] • [IMAGE] • [IMAGE] 1. 2. 3. 4. 10

  7. Andrew has several tables filled with data describing moving objects. Which table has data that describes an accelerating object? • [IMAGE] • [IMAGE] • [IMAGE] • [IMAGE] 1. 2. 3. 4.

  8. Which graph best represents a constant acceleration? • [IMAGE] • [IMAGE] • [IMAGE] • [IMAGE] 1. 2. 3. 4.

  9. A student observes an object moving. A graph of the movement is shown.Which best describes the motion depicted on the graph? • The object moves forward in a arc that extends to the left of the observer at a faster rate. • The object accelerates away from the observer from left to right before coming to a complete stop. • The object starts behind the observer and moves past the observer before returning to the starting point. • The object moves with a constant velocity in the negative direction then the positive direction then negative again.

  10. Car 1 is moving north at 100 kilometers per hour (km/hr). Car 2 passes Car 1 by moving at 110 km/hr in the same direction.From the frame of reference of the driver in Car 1, how fast is Car 2 going? • 210 km/hr • 110 km/hr • 100 km/hr • 10 km/hr

  11. A boat travels north at a rate of 25 kilometers per hour (km/h) relative to the current of the river. The current of the river moves south at a rate of 10 km/h relative to the ground. What is the rate of motion of the boat relative to the ground? • 10 km/h south • 15 km/h north • 25 km/h south • 35 km/h north

  12. A plane is flying east at a velocity of 350 km/hr. A passenger on the plane walks towards the rear of the plane at 3 km/hr.What is the passenger’s velocity relative to the captain who is flying the plane? • 3 km/hr • 12 km/hr • 347 km/hr • 353 km/hr

  13. To avoid a time delay, the larger jet refuels the smaller jet.What must the speed of the two jets be relative to the ground? • The smaller jet must be faster to align with the fuelling jet. • The fuelling jet must be faster to avoid spilling. • The speed must change depending on altitude. • The speed must be the same for both jets.

  14. An observer is watching a passenger moving on a moving sidewalk at the airport. The observer knows that the sidewalk is moving at 5 km/h yet the passenger appears to be moving at 12 km/h. Which would best explain what the observer sees? • The passenger is moving 7 km/h in the same direction of the sidewalk. • The passenger is moving 5 km/h in the same direction of the sidewalk. • The passenger is moving 7 km/h in the opposite direction of the sidewalk. • The passenger is moving 12 km/h in the opposite direction of the sidewalk.

  15. Two students are riding bicycles. The diagram shows their relative rates of motion.What is the westward rate of motion of Student 1 relative to the ground? • 8 km/h • 12 km/h • 20 km/h • 32 km/h

  16. A book is lying on a seat in a car that is moving at 50 kilometers per hour (km/h). The driver says that the book is not moving. An outside observer says the book is moving at 50 km/h because it is in the car. Which is the most logical conclusion for these two statements? • Motion is detected only if the car accelerates and is measured by the observer. • Motion is absolute, and the driver is incorrect saying that the book has no motion. • Motion is relative to a given frame of reference, and both the driver and observer are correct. • Motion is constantly changing so neither person’s statement will be correct when the car slows down.

  17. A train is moving south at 120 kilometers per hour (km/hr). Javier is walking at 5 km/hr relative to the train. Kassandra is moving toward the back of the train at 7 km/hr.From Kassandra’s frame of reference, how fast is Javier moving? • 2 km/hr • 12 km/hr • 125 km/hr • 127 km/hr

  18. A bus is moving east at a velocity of 100 km/hr. A passenger on the bus walks towards the front of the bus at 7 km/hr. A police officer is standing on the sidewalk as the bus passes.The passenger’s relative velocity is 107 km/hr to which person? • the driver of the bus • the bus passenger moving 0.2 km/hr east • the passenger in a car passing the bus at 120 km/hr • the police officer standing on the street as the bus passes

  19. The current of a river is flowing south at a speed of 10 kilometers per hour (km/hr). The speedometer on a motorboat moving north indicates the speed of the boat to be 14 km/hr. A person is traveling north on a bicycle along the riverbank.How fast must the bicycle rider travel so the boat and bicycle appear to be moving at the same speed to an observer on the shore? • 140 km/hr • 24 km/hr • 14 km/hr • 4 km/hr

  20. Dave is walking from the back of a train to the front of the train at a rate of 6 kilometers per hour (km/h). The train is traveling at a rate of 42 km/h. What is Dave’s speed, relative to the ground? • 7 km/h • 36 km/h • 48 km/h • 252 km/h
