• 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
• various materials to construct the racers
• Rules:
• The car must be powered by no more than 2 balloons. The balloons may only be blown up using lung power by the car operator. No other gases, such as helium, may be used.
• You can build the car out of anything, except a toy car or toy car parts.
• It must have at least three wheels. Wheels are defined as anything that is round and goes around.
• The wheels can not be wheels from a toy car. They must be made out of something that was not originally meant to be used as wheels.
• The car may not leave the ground.
• The car must be capable of traveling at least 5 meters.
• 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!
