This chapter focuses on the concepts of speed and velocity, including the difference between average speed and instantaneous speed. Through engaging practice scenarios involving a Velociraptor and space aliens, readers explore how to calculate average speed in real-world situations. Using formulas, you'll learn to determine time taken and distance traveled, enhancing your understanding of these fundamental physics principles. Whether it's calculating your escape from a dinosaur or the approach of extraterrestrials, mastering speed and velocity is essential!

  3. Why use Average Speed?

  4. Why use Average Speed?

  5. Why use Average Speed?

  6. Why use Average Speed?

  7. The Speed Triangle

  8. Instantaneous Speed vs Average Speed

  9. Speed vs Velocity 4m/s EAST SPEED VELOCITY

  10. Velocity SPEED VELOCITY DIRECTION

  11. Average Speed Practice While exploring a scary laboratory you discover some cages with the remainsof many lab-workers scattered about. While poking around within said cages youhear a noise. Looking up you see a Velociraptor entering the room 20 meters away. You flee in terror. If you can run at 4m/s, how far will you get in the 6 seconds It takes the Raptor to notice you. (assume that you notice the Velociraptor before itnotices you)?

  12. Average Speed Practice With fear you realize that you may not get away, you can now hear the animal Coming for you, and you have only had a 6 second head start! As you begin Fumbling to open a door that is in your way you hear the Raptor begin to run Towards you at 6m/s. How long does it take for it to catch up to you? In the last instant you manage To open the door and escape the Facility. You are now safe. Or are you…..

  15. Using What You Know… Evil space Aliens are approaching Earth! They are traveling at a speed of 500 km/hour How long will it take them to reach earth if earth is 18,000km away? Protect the Human race! What you know: Speed = 500 km/hour Distance = 18,000 km Time = ? Distance 18,000 km 36 Hours 500 km/hour Speed

  16. Using What You Know… The Doctor has asked you to travel back in time with him. You have travelled 132 miles in 1.5 hours. What is your velocity? Do you make? What you know: Speed = ? Distance = 132 miles Time = 1.5 hours Distance 132 miles 88 miles /hour 1.5 hours Time You’re going back to the FUTURE!!!

  17. Using What You Know… It is passing time, you want to go get a Egg McRipoff and can move at 2m/s, You have 60 seconds to make it and the Cat Stand is 150 meters away. Do you Make it? What you know: Speed = 2 m/s Distance = ? Time = 60 s Time 60 s Speed 2 m/s 120 meters Your tumbly will remain all rumbly!
