Newton s Three Laws of Motion

1. Newton�s Three Laws of Motion

2. Benchmarks and Standards (SCI.IV.3.MS.1) Qualitatively describe and compare motion in two dimensions. (SCI.IV.3.MS.2) Relate motion of objects to unbalanced forces in two dimension.

3. The Student will be able to: Identify Newton�s Three Laws Identify an Example of the Three Laws

4. You will Learn: 1st Law and an Example 2nd Law and an Example 3rd Law and an Example Smith�s 4th Law of Motion

5. Newton�s 1st Law Definition � objects in motion stay in motion, objects at rest stay at rest unless acted upon by an outside force. Also know as Inertia Newton�s First Law is Deductive Reasoning. The Law is given then the examples.Newton�s First Law is Deductive Reasoning. The Law is given then the examples.

6. Examples of the First Law A bowling ball is moving down the lane and will continue to�until it hits the pins and the backstop. The pins will stay standing up until the ball knocks them down.

7. Newton�s 2nd Law Definition � Force is equal to mass of an object multiplied by it�s acceleration. Force = Mass x Acceleration the faster something is moving � means it has more force the more mass there is�. The more force there is Deductive Reasoning Law shared, followed by ExamplesDeductive Reasoning Law shared, followed by Examples

8. Examples of the Second Law Football Players who protect the Quarterback are BIG!! Even though a golf ball is small and light, when traveling fast it hurts a lot when you get hit.

9. Example of Newton�s 3rd Law Inductive reasoning is here. There are examples first and then Newton�s Third Law is explained.Inductive reasoning is here. There are examples first and then Newton�s Third Law is explained.

12. Newton�s 3rd Law

13. First Law Quiz What is Newton�s First Law ? What is an Example of the First Law ?

14. Sorry Force = Mass x Acceleration Newton�s Second Law Action/Reaction Newton�s Third Law TRY Again

15. Correct Newton�s First Law is : Things in Motion Stay in Motion, Things at Rest Stay at Rest, unless it is Acted Upon by an Outside Force.

16. Correct The Pen will stay at rest until it is acted upon by an outside force.

17. Second Law Quiz What is Newton�s Second Law ? What is an Example of the Second Law ?

18. Sorry Inertia is Newton�s First Law Action/Reaction is Newton�s Third Law TRY Again

19. Correct Newton�s Second Law is : The force an object exerts is equal to it�s mass multiplied by it�s acceleration.

20. Correct The amount of Force that a Football player needs to break through the line and tackle the quarterback is found by taking his mass and multiplying it by his acceleration.

21. Third Law Quiz What is Newton�s Third Law ? What is an Example of the First Law ?

22. Sorry Inertia is Newton�s First Law Force = Mass x Acceleration is Newton�s Second Law TRY Again

23. Correct Newton�s Third Law is : For every action, there is an equal and opposite reaction.

24. Correct The ACTION is the bullet from the tank going forward. The REACTION is the tank being pushed back.

25. Mr. Smith�s Law Just Kidding.. There is no Fourth Law of Motion. Thanks for Playing
