5th Grade-Ch. 13 lesson 1 how can you describe motion Presentation Transcript

  • 1. Ch. 13 Lesson 1 How can you describe motion?
  • 2. types of motion ex: plucking rubber band vibrational motion ex: wheel circular motion moves back & forth ex : pendulum periodic motion moves in many directions & speeds variable motion
  • 3. vibrational motion plucking rubber band
  • 4. speed
    • how far object moves during certain amount of time
  • 5.  
  • 6. average speed = distance time
  • 7.
    • The fastest land animal, the cheetah, can run 70 miles in 1 hour.
      • speed= 70 = 70 mph
      • 1
  • 8. No Speed Limit: Introducing the Cheetah [01:09]
  • 9. Calculate the speed.
    • A sloth climbing 10 feet in 2 minutes
    • 10 = 5 ft/min
    • 2
  • 10. motion
    • measured in relationship to point of reference
  • 11. The passenger can use a tree as a reference point to decide if the train is moving. A tree makes a good reference point because it is stationary from the passenger’s point of view.
  • 12. velocity
    • speed & direction of an object’s motion
  • 13. Activity-Speeding Students 17 sec 20 sec 4 sec 5 sec 5 sec Time 20 m 20 m 20 m 20 m 20 m Distance 20 = 1.2 m 17 sec Anthony A (cartwheeled) 20 = 1 m 20 sec Ryan (crab) 20 = 5 m 4 sec Zachary 20 = 4 m 5 sec Taylor (ran) 20 = 4 m 5 sec Mrs. Holewinski Speed= d t Name

  • 15. Balloon Powered Race Cars
    • Materials:
    • standard 9 inch balloon
    • pen barrel or straw

    • Your car, with the completed entry form, is due on Tuessday, June 2.
    • Procedure:
    • You will use materials from home and assemble your car at home.  
    • On race day we will set up a track in our classroom. 
    • You will race in pairs against other classmates. 
    • Cars that follow all of the rules will be eligible for awards.  
    • These awards will be given in three categories.
    • 1. Best Looking Car
    • 2. Fastest Car (in first 5 meters)
    • 3. Farthest Distance Traveled
    Good Luck!
