You Bet Your Science Directions You are given

“You Bet Your Science!” Directions: ¨ You are given 200 points to start. ¨ You must bet on each question. ¨ Minimum bet is 1 point on each. ¨ Maximum bet is 10 points on each. ¨ Total up your points after each question. ¨ Winner is the one with the most points at the end of the game!

On your record sheet, write down your answer to each of the questions, and don’t forget to bet on how sure you are about that! So let’s begin… ¨ 1 On a distance versus time graph, distance is what variable? ¨ 2. What kind of relationship is between distance and time on the graph below?

¨ 3. Calculate the slope of the line for the graph below if the ending distance is 50 meters in 25 seconds. Include units. ¨ 4. What does the slope of the graph in the previous question represent?

And Yet More! ¨ 5. Centripetal Acceleration means a. Change in speed b. Change in speed and direction c. Change in direction d. None of the above

¨ 6. On a speed versus time graph, the slope of the line represents a. Speed b. Distance c. Time d. Acceleration ¨ 7. Calculate the distance a runner goes if their speed is 8 miles/hour and they ran for 1. 2 hours.

More questions! ¨ 8. Describe the motion of a car in the graph below if the distance it travels is plotted versus the time it travels.

¨ 9. What is the difference between speed and velocity? ¨ 10. Calculate the acceleration of a car that is traveling at 60 mph and has to change its speed to 25 mph in 2. 2 seconds when a deer jumps in front of it.

Be sure to make your bet! ¨ 11. How long will it take a plane to travel 420 km if its speed is 540 km/h?
