  2. What is the line of displacement? A STRAIGHT LINE FROM THE INITIAL POSITION (START) TO FINAL.

  3. A speedometer is used to measure what kind of speed? INSTANTANEOUS

  4. What are three ways an object can accelerate? INCREASE SPEED DECREASE SPEED CHANGE DIRECTION

  5. You walk from school to the library. What are the directions between the two locations? East and North

  6. How many dimensions did you travel? Two dimensions

  7. Which of the following would you NOT use as a reference point for describing the location of the parked car? THE BIRD; IT IS NOT STATIONARY

  8. A turtle takes 35 minutes to travel 175 meters. What is the speed of the turtle?

  9. What is the average speed of the following graph?

  10. What does the line in the graph above indicate? LINE ON DISTANCE VS TIME GRAPH INDICATES SPEED. DIAGONAL LINE INDICATES CONSTANT SPEED.

  11. If the car is traveling at a constant speed, what is that telling you? THE CAR TRAVELS THE SAME DISTANCE IN A SPECIFIC AMOUNT OF TIME; FOR EXAMPLE, A CAR TRAVELS 25 KILOMETER EVERY HOUR.

  12. Velocity includes ________and____________. DIRECTION SPEED

  13. Identify whether the following examples are balanced or unbalanced. Balanced Balanced Unbalanced Unbalanced

  14. How can we increase the gravitational force acting on two objects? • INCREASE MASS • DECREASE DISTANCE

  15. The following formulas related to which of Newton’s Laws of Motion? • A=F÷M F = M x A M=F÷A Newton’s Second Law of Motion

  16. If you push a box to the right. Which direction is the force of friction acting? LEFT

  17. Which type of friction prevents surfaces from sliding past one another? Static

  18. Which type of friction acts on objects that are not in motion? Static

  19. Why do objects in motion stay in motion and objects at rest stay at rest? Inertia

  20. When calculating net force, when forces act in the same direction we ______and when forces act in opposite directions we ____________. ADD SUBTRACT

  21. A ball rolls 3 meters in 2 seconds and 7 meters in the next 3 seconds. What is the ball’s average speed?

  22. During a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25s.  What is the sprinter’s accelerationduring this period?

  23. A boy pushes a box with a mass of 16 kg and it moves at an acceleration of 3.2m/s2. With what force does the boy push on the box? F = M x A F = 16 kg x 3.2 m/s2 F=512 N

  24. A baseball bat has a mass of 2.5 kg. The player swings the bat with a force of 87.5 Newtons. What is the acceleration?

  25. Olivia ran down the hill with the acceleration of 250 m/min2.. She applied 14,000 Newtons of force. With this information calculate Olivia’s mass?

  26. Brian has a mass of 83 kg on Earth. What is his weight? F = M x A F = 83 kg x 9.8 m/s2 F=813.4 N
