  1. FORCE & MOTION P-SELL Big Idea 13 Student Book p. 63

  2. What is MOTION? • Always a change in the position of an object. • Sometimes it may involve a change in direction, too. P-SELL Big Idea 13 Forces and Motion Student Book p. 63 Department of Mathematics and Science

  3. What changes motion? • Motion of an object changes when a force acts upon the object. • An object remains in motion, or at rest, unless a force acts on it. Object in motion

  4. What are Forces? Forces are a push or a pull. • What happens when you hold up a book and drop it? • What happens when you drop two books with different masses? • Will they land at the same time or different times? • Does this work every time with any two objects? • What happens if you drop a book and a piece of paper at the same time? • What if you crumple up the piece of paper? Now let’s visit the astronauts on the moon testing this out: Hammer vs Feather - Physics on the Moon • Why does this happen? Now let’s look at a virtual experiment Galileo Drops the Ball What did Galileo learn? Galileo found any two objects will land at the same time. Earth’s gravity will pull harder on the object with the greater mass and the one with the smaller mass will have less force of gravity acting on it. What force can affect the pull of gravity? • Air resistance or friction How does the force of friction impact an object’s motion? • Friction works against gravity and slows down moving objects.

  10. ClaimEvidence Reasoning (CER) Assignment Part 1 • Find force and motion investigation notes in your journal. • Watch the Discovery video: Friction • Do the Discovery Exploration: Changing the Speed of Motion. • Last read the articles: Zamboni and Now That’s Fast. Be prepared to use evidence from what you investigated, read, heard and saw to support your answer to one of the following questions: 1. How does the force of friction change the motion of an object? 2. How do different forces cause objects to change speed?

  11. Moon Earth • Amount of mass • Type of force applied • Type of surface texture • Surface area What conditions can affect force and motion? (Study Jams) Pulling Your Weight DE virtual lab

  12. What are Magnets?Let’s Explore!(SC.4.P.8.4) Write down your observationsas you explore. • What happens if you put together two magnets? • Turn one of the magnets around and do step 1 again. What happened? Was it the same? • Experiment with different magnets and a bag of objects. Click to open P-SELL Student Book Magnetic Forces p. 79-81

  13. What do you know about the force of Magnetism? • Magnetism is a force. • Metals stick to magnets. • Magnets have different strengths. • Magnets have two poles: north and south. • Like poles repel. • Opposite poles attract. • The force of magnetism can travel through some objects.

  14. What is Magnetism? Magnetism is the force of attraction or repulsion of a magnetic material due to the arrangement of its atoms. What are some everyday uses of magnets?

  15. FCAT Review 1. Jordan makes the following list of choices for the science fair. Which choice would be scientifically testable? • What do 5th graders think of playing tug of war? • Which type of stone is the best looking in my rock collection? • Does a ball roll farther on grassy PE field or on a asphalt basketball court? • Is Mrs. Jones a nicer teacher than Mr. Mathews?

  16. FCAT Review 2. Ricardo is conducting an experiment to see how far a rubber ball will roll when he releases it at the top of an inclined plane. Why does the ball speed up as it travels down the inclined plane? • The force of gravity pulls the ball down the inclined plane. • The force of friction is reduced because the ball is rubber. • The ball has less magnetic attraction to the plane as it travels. • The ball has a greater mass as it travels faster.

  17. FCAT Review 3. Charlene kicked the winning goal in her last soccer game. What force acted between Charlene's foot and the ball to cause the ball to move? • Gravity • Magnetism • Pull • push

  18. FCAT Review 4. Tiffany is helping her parents to unpack some boxes. She lifts a full box with a mass of 15 kilograms. She empties out about half of the items from the box and lifts it again. Which is true regarding the force she applies after unloading the box? • She has to apply a different type of force after changing the mass. • She has to apply more force to lift the box because the mass is greater. • She has to apply less force to lift the box because the mass has decreased. • She has to apply the same amount of force to the box to overcome gravity.

  19. FCAT Review 5. Maria roller skates to the top of a hill and then starts rolling downward. What are the MAIN forces affecting Maria’s motion as she rolls down the hill? • gravity and magnetism • speed and friction • friction and gravity • push and pull
