3 Unit 1: The Nature of Science (Distance, Speed, Velocity) Vocab Average speed - The speed calculated for an entire trip. (The total distance divided by the total time.) Unit: m/s Bar graph - Chart that shows comparisons between different groups Constant velocity - When velocity does not change Quizlet shortlink: Distance - The amount of space between two objects. Units: m (meter) Instantaneous speed - How fast an object is moving at any particular moment. Can be measured with a speedometer or radar gun. Unit: m/s Line graph - Chart that is best for looking at one thing over time (Example: stock prices) Liter (L) - Unit of Volume Meter (m) - Unit of Distance Pie graph - Chart that is best for showing parts of a whole or percentages Seconds (s) - Unit of Time. Speed - How fast you move. Distance compared to time. Unit: m/s Velocity - Describes both speed and a direction. Unit: m/s Volume - Amount of space an object takes up. Unit: L (liter) 3

6 Solving for Speed 1. What is the velocity of a cheetah that can travel from North St. Paul to Target Field 27, m in s? List your variables and their values. Write the equation you will use. Show your work. Answer (with units) 2. The International Space Station (ISS) travels at 7,661 m/s and it took s to go from above Mt. Rushmore to above the White House. What is the distance that it traveled? List your variables and their values. Write the equation you will use. Show your work. Answer (with units) 3. The Marcus Oakdale theater is km from North High School. A mosquito can travel at 0.54 m/s. How long will it take for it to fly there and bite you? (Hint: convert km to m) List your variables and their values. Write the equation you will use. Show your work. Answer (with units) Continue to show all 4 steps 4. The Mississippi river is km long and travels at an average speed of m/s. How long will it take to float down the whole way? 5. A zombie is stumbling toward you at you at rate of m/s. How far can he shamble in 2 minutes (120 s)? 5 minutes (300 s)? 1 hour (3600 s)? 6. The sun is 147,098,074 km from Earth. Light takes seconds (~8 minutes) to reach the sun from Earth.

11 Distance Complete the practice test review below AND the digital component here 1) Draw an example of a bar graph, a pie chart (circle graph), and a line graph. 2) When should you use a line graph? When should you use a pie chart? 3) What is the difference between speed and velocity? 4) What is the difference between average speed and instantaneous speed? 5) How do you calculate average speed? 6) How do you find instantaneous speed? Draw a Distance vs. Time line graph below and plot the motion of 4 cars racing on it. Car A: Maintains a steady speed from start to finish. Finishes in 4 th place. Car B: Starts a high speed, but has engine trouble and slows down. Finishes in 3 rd place. Car C: Starts at a medium speed, but has engine trouble and stops for a few seconds. Resumes racing at a much higher speed. Finishes in 1 st place. Car D: Accelerates the entire race. Finishes in 2 nd place. Which car has the highest average speed? 10 Time
