  2. 10th – 11th grade high school students • Approximately ages 15 – 17 • Previous experience required in basic math, Algebra I Target Audience Main Menu Next

  3. Preferred: classroom with computers, students can ask teacher to clarify lesson if needed • Secondary: home computer with PowerPoint capability Learning Environment Main Menu Next Last

  4. After learning Newton’s 1st Law of Motion, students will answer quiz question 1 with 100% accuracy. Objective 1 Main Menu Next Last

  5. After learning Newton’s 2nd Law of Motion, students will answer quiz question 2 with 100% accuracy. Objective 2 Main Menu Next Last

  6. After learning Newton’s 3rd Law of Motion, students will correctly identify one action-reaction pair in quiz question 3. Objective 3 Main Menu Next Last

  7. Start Here! The First Law The Second Law The Third Law Take the Quiz! Newton’s 3 Laws of Motion References

  8. Motion is a part of everything we do. • Today, we’re going to learn about three basic laws, which were discovered by this guy: Why Learn About Motion? Plus... It’s fun! Main Menu Next

  9. Welcome to Newton’s 1st Law of Motion! It’s time to learn about INERTIA. Later we will study his 2nd and 3rd laws. Newton’s First Law of Motion Main Menu Next Skip to Quiz

  10. The law of inertia states that “an object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an outside force”. Law of Inertia Main Menu Next Last Skip to Quiz

  11. When you start rolling a ball, it continues to roll. Hence why you sometimes have to chase it across the street. • Things that are stopped stay stopped. The ball doesn’t move until you push or kick it. What does this mean? Main Menu Next Last Skip to Quiz

  12. Question: If a car is speeding down the street and has no driver, does it stop at red lights? • Answer: NO. An object in motion will stay in motion. The car will continue to move unless someone hits the brakes. Inertia Example Main Menu Next Last Skip to Quiz

  13. Now that we’ve learned about Newton’s First Law of Motion, it’s time to consider those “outside forces” that can change an object’s motion. The 2nd Law Law of Inertia Main Menu Last Skip to Quiz

  14. You should already know about inertia. Now it is time to learn a little bit about forces before moving on to Newton’s 3rd Law. Newton’s Second Law of Motion Main Menu Next Skip to Quiz

  15. Newton’s 2nd Law is about the strength of forces. This law is pretty intuitive. You already know that a large, heavy object is harder to lift than a smaller one. Now it is time to find out why this is true. Forces Main Menu Next Last Skip to Quiz

  16. Newton had an equation to find the numerical value of a force. F = m x a force acceleration, or rate of change in motion mass of the object Forces Main Menu Next Last Skip to Quiz

  17. Forces: newtons (N) • Mass: kilograms (kg) • Acceleration: meters per second squared (m/s2) gravity = 9.8 m/s2 Force Units Main Menu Next Last Skip to Quiz

  18. To solve for a force, you will be given a mass an acceleration to multiply together. • Question: What force does a 65 kg person exert on the ground after falling off of a cliff, accelerating at 9.8 m/s2? • Answer: Force = 637 N Force Example Main Menu Next Last Skip to Quiz

  19. Now you know that to change an object’s motion you need to accelerate its mass with a certain force. Let’s learn about how forces interact with each other next. The 3rd Law Forces Main Menu Last Skip to Quiz

  20. Now that we’ve learned about how forces change an object’s motion in Newton’s first and second laws, let’s move on to how forces interact with each other. Action-Reaction Pairs Main Menu Next Skip to Quiz

  21. Newton’s 3rd Law states that “for every action, there is an equal an opposite reaction”. Action-Reaction Pairs Main Menu Next Last Skip to Quiz

  22. Think about it. When you lift something up with a certain force, don’t you feel that object pushing back down on you? Action-Reaction Pairs Main Menu Next Last Skip to Quiz

  23. PAIR: gravity and the normal force. • PAIR: you punch the wall, and the wall hurts your hand. • NOT a pair: your friend hits you and you hit him back. Take the Quiz! Examples of Action-Reaction Main Menu Last

  24. Now that you’ve learned a bit about Newton’s 3 Laws of Motion, it’s time to test your knowledge. Start the Quiz!

  25. Which of these choices is an example of inertia? • A) you catch a flying ball • B) a car brakes to stop at a red light • C) a person falls through the air • D) after the skater gets off, a skateboard continues to roll Question 1 Main Menu

  26. The correct answer was (D). • You definitely know Newton’s 1st Law! Great job! Main Menu Next Question

  27. Remember: “objects in motion stay in motion”. • Hint: gravity exerts a force! Oops! That’s not quite right. Main Menu Try Again

  28. Imagine your car runs out of gas. If it weighs 1500 kg, and you push it with a = .05 m/s2, what force are you pushing with? • A) 0 N • B) 75 N • C) 100 N • D) 50 N Question 2 Main Menu

  29. The force you push with is 75 N. • Although whether you can actually push a car is another question entirely. ;) Good Job! Main Menu Next Question

  30. Remember: F = ma. • Check your math to make sure you did it right! Oops! That’s not quite right. Main Menu Try Again

  31. Which of these choices is an action-reaction pair? • A) gravity and the normal force • B) you punch your brother and he punches you back • C) you kick a ball and it moves forward Question 3 Main Menu

  32. The normal force is the force that opposes gravity. • You know your force pairs! Awesome! Main Menu Finish

  33. These can be tricky! • Hint: the two forces must go in OPPOSITE directions. Oops! That’s not quite right. Main Menu Try Again

  34. You’ve finished the quiz! You are now an expert on Newton’s Laws of Motion. Congratulations! Main Menu
