Motion ______ –distance over time _______ – speed and direction __________ – the rate at which velocity changes

Motion Calculate the total velocity for each of the passengers. 0km/h west 5km/h east 4km/h west Airplane: 800km/h west

Motion • QUICK REVIEW • What information must you know in order to calculate speed? • What is the error in the following statement: • The velocity of the car is 55km/hr.

Motion Application: Speed Calculations A pitcher threw a baseball 150m in 2 seconds. How fast was the ball going? A girl can run 50m/s. How long will it take her to run 1000m? You drove 80km/h for 3 hours. How far did you go?

Mini quiz! Application: Speed Calculations A car drove 120 miles in 3 hours. How fast was it going? A sprinter can run 60 m/s. How long will it take her to run 600m? You drove 50 mi/h for 8 hours. How far did you go?

Motion Application: Speed Calculations How fast would you have to drive to go from Atlanta to New York (900 miles) in 10 hours? A red car drove 150km at a speed of 50km/h. A blue car drove 300km at a speed of 75km/h. Which car reached its destination first?

Motion Application: Speed Calculations A plane flies 100 km east for 10 minutes, then 200 km for 10 minutes, and then 50 km for 5 minutes. What is the plane's average velocity? Did the plane accelerate?

Motion Application: Speed Calculations You will drive to a town that is 100km away. Half the trip you will be able to drive 100km/h (on the highway) and half the trip you will drive 50km/h (going through small towns). How long will it take you to get there? Show your work!

Motion Distance-Time Graphs ---- Car 1 ---- Car 2 Graph showing the speed of a car • Which car drove at a constant speed? • Which car accelerated? • Which car is faster? How do you know? • Which car drove farther after 1 hour? After 6 hours? Distance (km) Time (h)

Motion Distance-Time Graphs Calculate the average speed at each point: _________ _________ _________ _________ Did the car accelerate or stay at a constant speed? How do you know? D C B A

Motion • Distance-Time Graphs • The following graph shows the distance Kyle traveled on his bicycle trip and the amount of time it took him to travel that distance. During which 5-minute interval did Kyle achieve the greatest average speed? What may have happened between t = 10 and t = 15 minutes?

Motion Quiz What two things must you know to calculate speed? What is wrong with the following statement: The velocity of a car is 100km/h Turning left, slowing down, and speeding up are all examples of __________. How fast would you have to drive to go from Atlanta to New York (900 miles) in 9 hours? A red car drove 400km at a speed of 50km/h. A blue car drove 600km at a speed of 75km/h. Which car reached its destination first? YOU MUST SHOW YOUR WORK FOR CREDIT!

Motion Quiz • Which car drove the farthest after 1 hour? • How far did each car drive in 7 hours? • Red Car _____ • Blue Car: ____ ---- Blue Car ---- Red Car Graph showing the speed of cars Which car accelerated? Which car stayed at a constant speed? What best explains the motion of the red car between t=1 and t=4? Distance (km) Time (h)
