Hey class, I hope all is well and that we are all staying healthy and safe. I know it is not easy staying in, but maybe take a walk on this beautiful day. There is a lot of learning/exploring you can do by just taking a walk/going outside. This last demo is full of vocabulary terms and Newton's Laws of Motion. Can you identify any of them in this video. This is my last demo for the week. Are they helping you apply this concept better? ***HAPPY BIRTHDAY BAXTER*** :)

I believe that when you hit the hammer on the book, it didn't hurt you hand because the book absorbed the blow as well as the force was being equally distributed. It's sort of like when you see people walking on the eggs and them not cracking, it's because the weight of the force was evenly distributed across them.

MaCartney you went in a different direction, which was correct. However, here is my question for you...which object was not moving? This will help apply to one of Newton's three laws. :) Loved your example keep up the good work and thinking. (Your response was more about momentum - something we have not learned yet)

The part where you were playing tug of war with your daughter showed Newton's first law because your forces were ubalanced, and you clearly had a greater net force than Amelia, so it went in your direction.

Jessica, another true statement with the correct law...my question for you though. I "pretended" that Amelia and I were at an impasse where neither of us could move. We both had equal forces. Would this be the same law?

When you and Amelia were playing tug of war, you had the greater amount force so you won. That’s demo was a representation of Newton’s 1’s law of motion which states that an object at rest stays at rest and an object at motion stays at motion unless acted upon by an unbalanced force.

Marleigh you gave me a great and accurate response. I liked how you even went on defining it for me to help give your answer validity. My question for you is the same as Jessica's- in the demo I 'pretended' to be at an impasse with Amelia where we both had equal forces. Would the law still remain the same?

When you and Amelia were playing tug of war, the rope did not move due to you both pulling on it. Since the force was balanced, the blanket did not move. The blanket followed Newton's law of Inertia. When you "punched" the weird looking thing, it went down then back up to your fist. This showed Newton's third law of motion of every action has an opposite and equal action. Regarding the book, the reason you didn't feel anything was due to the book returning the same force back to the hammer and the impact being absorbed by the book, allowing your hand and Amelia's hand to not feel any impact.

Tug of war represented Newtons 1st law, the second demo, with the soda thing showed Newtons 3rd law of equal and opposite reactions and the books absorbed the force of the hammer which is why you and Amelia didn’t feel it. That would be Newtons 2nd law.

Sam, I do not disagree with what you said, but evidence to back it would have helped. Tug of war can be Newton's first and third law...do you see how? The book and hammer described inertia which is part of the first law...however, if you gave me proper evidence I could see your reasoning behind this!

In the first demo, you were displaying Newton's first Law. An object in motion will stay in motion, which is why Amelia kept moving backwards after you let go of the blanket thingy. If you were both pulling on the blanket equally then inertia would keep both from moving. The punching bag demo displayed all three laws, but especially the third one. When you punched the punching bag, the force of your punch had an equal and opposite reaction on the punching bag which is why it fell backwards and came back up. The third demo with the hammer and the physics book also displayed the third law because the impact of the hammer was spread out equally across both books which limited the amount of force that was exerted on to you and Amelia's hands.

The tug of war demo demonstrated Newton’s 1st law of motion. You had the greater force meaning that the forces between you and Amelia were unbalanced. This why you won and pulled Amelia.

Destiny, correct statement but can it be applied to any other law? Think bigger? Bring in the concepts we learned.

When you were playing tug of war your force was greater so you pulled Amelia towards you and that represents newton's first law of motion.

Justin keeping answers short and sweet helps you get a correct response. However, can tug-of-war ever be a different law? What about if Amelia and myself had the same force and we were at an impasse? Would the law stay the same?

The demonstration when you were playing tug of war demonstrated Newtons first law of motion. During tug of war you had the greater force so you and Amelia's forces were unbalanced. That is why you were able to pull her and why you won.

Kortlyn, what you said was accurate. I cannot fault you on anything you said. However, if Amelia and myself had the exact same force, would the law change?

You demonstrated newtons first law of motion when playing tug of war with Amelia. You and Amelia had an unbalanced amount of force. Yours was stronger which is why you won.

Olivia great response and accurate. However think about what caused Amelia to move. Think about if we had the exact same force and at an impasse, would that change the law?

The first demo when you and Amelia were playing tug of war demonstrated Newton's first law of motion. You had a greater force therefore you were able to win.

Kelsie great post and explaining why it is that law. However, can you explain to me what caused Amelia to move/ what happens if we exerted the same force? Would the law then change?

The first demonstration was an example of Newton;s first law of motion also the law of inertia. This was because Mrs.Holder had a greater force than Amelia which is why she won the game. The second demonstration was an example of the second law of motion because the amount of force that was given to the inflatable thing was much more than needed for it to move. What i mean is that all the force that was given with the little amount of mass created a greater acceleration for it to lean backwards.

Edna, There is a misapplication of Newton's First Law. Remember an object in motion will stay in motion or an object at rest will stay at rest. The final phrase "unless acted upon by an outside force" applies to when an object moves. This is really Newton's second law (F=ma). Inertia is a property to resist movement or the stop in movement. Consider why neither person moved in the tug-of-war. You are right with the lack of movement, but why? Think in terms of a balanced or unbalanced force. Awesome job understanding the punch meant a greater acceleration with a smaller mass. But was the fist the only thing that was hitting? Just food for thought.

For one to explain back, one must understand a topic at it's fullest potential. But for one not to be able to put it into words, one must be able to find a deeper understanding to the topic.

Oh this response Machi, it made me smile..one must understand this concept to the fullest potential to respond to these demos. For this I can agree with you upon. I think understanding Newtons three laws you must. Let me know if you need help! (Did my inner yoda work? I think not, but I gave it a go.)

When Mrs. Holder shows us playing tug of war with her daughter it shows Newton's first law of motion which shows that an objects will remain in their state of motion unless a force acts to change the motion. Then, the second demo shown was Newton's second law of motion because the thing is coming back to where it was. So, the same direction as the net force, and inversely proportional to the mass of the object.

Audrey, Inertia is the property of an object to be at rest or at motion. The more massive the harder to move, the less massive the easier to move. Was the rope massive in the tug-of-war game? Did that make it not move? Consider Newtons Third law as you answer those questions. If someone were to let go - the balances are unbalanced (hint hint) and there was a force applied to a mass. You could argue F=ma with the punch and you would be right. Food for thought though, was the fist the only thing being hit in that demo?

In the second demo where you were hitting the punching bag, the punching bag didn't move until you made it move which was you punching it. So the second demo applies to Newtons first law.

Jayden, I agree with your statement. However my question for you is, can it be applied to any other law? How can you see the first law or even the third in that demo segment? Think bigger. Great job.

The first demo had been an example of Newton's first law since the force between Mrs. Holder and Amelia was unbalanced which had caused Amelia to fall in motion. Then the second demo had represented the second law since the clowns acceleration to get back up had changed with the difference in force and mass. While the third demo had represent the third law since Mrs. Holder had used force on the book where then the second object being the book gave and equal and opposite reaction to the hammer.
