  1. Speed and motion Review

  2. John is driving East on I-30 at 75 mi/hr, he misses his exit so he turns around and starts driving West at 75 mi/hr. What happens to his speed and velocity? The velocity of the car changes, but the speed stays the same.

  3. What is the average speed after 6 seconds? No 1 km/sec Is the object accelerating?

  4. What will be the result? 10 N 15 N The box will move to the right with a force of 5 N

  5. What causes an object to accelerate? Unbalanced forces

  6. Which graph best represents the motion of an object whose speed is increasing?

  7. Draw a speed time graph that shows someone walking at a constant speed and the speeding up to a faster constant speed. S P E E D TIME

  8. How do you determine velocity of an object? Calculate speed and add in direction Ex. 10 m/s North

  9. Which of the following statements regarding the car’s motion is true? The velocity of the car changed, but not the speed. The speed of the car changed, but not the velocity. The velocity and the speed of the car changed. The velocity and the speed of the car stayed the same.

  10. Shannon runs 50 meters in 10 seconds, what is her average speed? 5 m/s

  11. List the formulas for calculating Speed, Distance, and Time. S=d/t D=s x t T=d/s
