Transcription of 3: Newton’s Third Law of Motion
1 3: Newton s Third Law of MotionDay 1:Warm Up: Write something fun you did this weekend!LT: I can explain Newton s Third Law of MotionNewton s CradleTHINK independently and then DISCUSS with your is happening? is this happening? forces are working?Newton s Third LawFor every action, there is an equal and opposite Force-Initiating force (first force)-Causes the reaction forceEx1 : baseball hitting bat (action),Ex2: Gymnast jumping off beamFORCES ALWAYS COME IN PAIRS! Reaction Force-Reacting force (second force)-Responds to the action forceEx1 : bat applying force on ball after the ball hits itEx2: Beam exerting force on gymnastFORCES ALWAYS COME IN PAIRS! THERE IS ALWAYS A REACTION FORCE EVEN IF IT ISN T OBVIOUSW hich is the action and reaction force?
2 Bowling ball pushing over pin - ActionPin pushing bowling ball - reactionBall pushes glove - actionGlove pushes ball - reactionWhich is the action and reaction force?Answer: A - action, Ball - C - action, Ball - reactionIdentify at least 6 pairs of action-reaction pairs in the following diagram:Action - Reaction Pairs WSFootball Physics: Newton s Third LawFootball physics: 2:Warm Up: What is Newton s Third Law of MotionLT: I can explain Newton s Third Law of Motion and give examples of action-reaction pairs. Review: Newton s Third LawFor every action, there is an equal and opposite over Action - Reaction WS HW and Turn InInvestigate car Crash mythbusters: with your group to choose one example (check in with Ms.)
3 P once you have picked), EXPLAIN and MODEL how your chosen example shows Newton s Third Law (use white board!) crashing into a hitting earth s player hitting bee stinging your dog catching a eagle catching a basketball player shooting a jet taking off from the flying squirrel landing on a tree motorcycle crashNewton s 3rd Law WSDay 3: Car Crashes + Test Review + Egg DropWarm Up: Write an example of an action-reaction pair and Newton s Third Law of : I can use Newton s Three laws to explain why the bobsled Bobsled revisionPhysics of a bobsled: your bobsled a CER about WHY the bobsled crashedNewton s Laws in SPACE!

4 -Who Sir Isaac Newton was-Newton s Three Laws of Motion - what they are and how they work-All the equations we have used -Speed, distance, time-Velocity-Acceleration-Force-Gravity -Friction-Mass-Action Force-Reaction ForceProject: Egg DropTask: Design a container and parachute to carry a raw egg to ground when dropped from 15 ft. Goal: Slowest time and safest landingRequirements: Work with your team, use only acceptable materials, container must fit in backpackProject: Egg DropMaterials: see list on instructions, any other materials must be approved by Ms. YOUR MATERIALS WITH YOU TO CLASS Ms. P will provide egg on the day of the drop (March 13)Due Dates: Egg drop: March 13, Write up due: March 14 Day 4-5: Egg Drop Work DaysWarm Up: What are some of the requirements for the egg drop project?
