Physical Science Study Guide – Chapter 2
Chapter 2 Study Guide
1. Be able to identify the difference between distance and displacement.
2. Be able to explain the difference between speed and velocity.
3. Be able to interpret motion graphs. See pg. 41 Fig. 3
4. Be able to convert from km to miles or meters to feet using dimensional analysis.
5. Why is a frame of reference necessary to detect motion?
6. Be able to calculate speed problems. Practice problems may be found on pg. 40.
7. What is the difference between average speed, instantaneous speed and constant speed?
8. When objects travel in a circular direction, what is changing?
9. Acceleration may be described in three ways. What are they?
10. What are the formulas for speed and acceleration?
11. A freight train traveling with a velocity of 18.0 m/s to the south begins braking as it approaches the train yard. The train’s acceleration while braking is -0.33m/s2. What is the train’s speed after 23 seconds?
12. The elevators in the Landmark Tower in Yokohama, Japan are among the fastest in the world. They accelerate upward at 3.125 m/s2 for 4.0 seconds to reach their final speed. If these elevators start at rest, what is their final speed?
13. An automobile manufacturer claims that its latest model can go from 0 to 90 km/hour in 7.5 seconds. What is the car’s acceleration in m/s2? (Be careful, watch your units!)
14. A fighter jet landing on an aircraft carrier’s flight deck that has a length of 300.0 meters must reduce its speed from about 42.5 m/s to exactly 0.0m/s in 2.0 seconds. What is the jet’s acceleration?
15. A runner whose initial speed is 29 km/hour increases her speed to 31 km/hour in order to win a race. If the runner takes 5.0 seconds to complete this increase in her speed, what is her acceleration?
16. The Impact is the first electric car ever developed. During tests in 1994, the car reached a top speed of nearly 296 km/hour (82.2 m/s). Suppose the car started at rest and then underwent a constant acceleration of 1.6 m/s2 until I reached its top speed. How long did it take Impact to reach its top speed?
17. How long does it take a bird to fly 300km if it travels at a speed of 50 km/hr?
18. Alex rode his bicycle 60 kilometers in 4 hours. How fast was he going?
19. Matt says he is faster than Alex. He rode 90 meters in 6 minutes. What is Matt’s speed, and is he faster than Alex?
20. Joe can pitch a baseball a distance of 48 meters in 1.5 seconds. How fast is his pitch?
