@2:20, Amelia isn't going to get wet if she pulls the table cloth fast enough, so that the water doesn't get pulled off along with the table cloth as well.

Amelia Didn't pull the cloth fast enough so the glass cup didn't come off.the motion was not fast enough as well as the Force was strong enough

You are correct, Amelia did not pull this fast enough and would have gotten wet. Great job using the word motion which is important in Newtons Law's. The biggest vocabulary term I need you to understand is inertia with this law. Great first post thanks!

Amelia didn't pull the cloth with enough speed so even if she did manage to pull the cloth all the way it would have still gotten her wet, which is why when Mrs. Holder pulled it fast it didn't wet her.

Amelia didn't pull the cloth fast enough to the point where she would get wet but even if she did pull the cloth completely off the table she would have still gotten wet because she didn't have enough speed. mrs. holders speed was much faster which is why she didn't get wet

Hey Cooper! Great job using the word "pull" because this is all about the push/pull of a force on an object at rest. Thanks for addressing the correct reason why I did not get wet. Make sure to know the term inertia. Thanks for sharing.

According to Newton’s First Law “an object at rest will stay at rest and an object in motion will stay in motion, unless acted on by a force that speeds it up, slows it down or changes its direction“. For example, in the cup and table cloth experiment the inertia causes the cup of water to stay on the table cloth even though it is moving. The reason that it it did not work the first few times is because during the experiment, the speed/movement of the table cloth slowed down which altered the inertia causing the cup to move with the cloth. But, the experiment worked the third time because the movement of the cloth was constant and be never slowed down, sped up, or changed direction which caused the cup to stay in the same place while the table cloth was still moving.

Joy thank you for such a great post. I can see from this you understood what Newton's first law of motion stated and why these demos showed it. You even explained why Amelia was not successful due to her speed. Did you know I was able to do that on my first try and not get wet! Gotta love science.

This applies to Newton's first law of motion because the cup and the coin stayed at rest when the cloth and the card were removed because the cup and the coin were at rest in the beginning and the cloth and the card were acted upon, not the cup and the coin.

The demo applies to the fist law of motion with the penny and the cup ,you move the card slowly, it isn't fast enough to overcome that force. But If you flick it quickly, the coin stays in one place and then drops into the cup this shows inertia and how the first law says."An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."

According to Newton's first law of motion, "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force," the glass cup was able to stay on the table because of inertia despite the tablecloth's speeding motion. It didn't work the first time because Amelia slowed down when she pulled the tablecloth which caused the cup to move as well; however, when Mrs. Holder pulled the tablecloth, the cup did not move because the movement was quick and constant. The force of friction is also small which makes it easier for the tablecloth to move underneath the cup.

Newton's first law states that an object will stay in uniform motion unless acted on by an unbalanced force. The glass cup did not move because the speed of the table cloth was constant. When Amelia and the guy in the video did it, the tablecloth was pulled at a slower speed which caused the glass to go with it. When you pull the cloth, friction between the cloth and the bottoms of the glass acts on it for a short time in the direction of the pull. So the force of friction is small and the cloth slides out from underneath the glass without dragging it.

This correlates to Newton's first law of motion because Mrs.Holder had to pull the tablecloth with speed and force in order for it to move quickly and not spill the water. Newton's first law states that nothing can be moved or stopped without an external force moving it. That is how Newton's first law correlates to this demo.

This demonstration applies to Newton's first law of motion. The reason Amelia would have gotten wet if she fully pulled the cloth is because she did not pull the cloth with enough speed to overcome the weight of the cup. the reason the cup stayed in place when you pulled it was because you pulled it fast enough to where the cup didn't have enough time to build up in speed and move out of its place.

Newtons first law of motion states that an object won't move until another force is applied to that object. So when Amelia moved the table cloth,(or at least tried to) the glass moved. The glass wasn't moving when the cloth,(the force) was still. The same applies for the envelope and the penny. When Amelia pulled the envelope fast, the penny didn't have enough time to react to the motion. As a result the penny fell into the glass

The cup did not move because Ms. Holder pulling the cloth was constant and did not have much friction. However, when Amelia did it, she changed speeds which was not constant and led to a lot of friction and led to the cup moving with the tablecloth.

According to Newton’s First Law “an object at rest will stay at rest and an object in motion will stay in motion, unless acted on by a force that speeds it up, slows it down or changes its direction."Amelia did not pull the table cloth fast enough so the glass moved with it thus, representing Newton's first law.

The demo worked when Mrs.Holder pulled the cloth because of inertia. In Newton's First Law of Motion he described inertia as the tendency of an object at rest to remain at rest unless a force acts upon the object to move it. Inertia for an object in motion is the tendency for that object to remain in motion, unless a force acts on it to speed it up, slow it down, stop it, or change its direction. In terms of the tablecloth trick, inertia is was the key. The inertia of the glass on the table kept it where it was despite the speeding tablecloth underneath it.

Newton’s first law of motion states that “An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an unbalanced force”. This law applies as to why the cup didn’t move off the table when Amelia pulled the table cloth, and why it did when Ms. Holder pulled it off. Amelia pulled the tablecloth too slow which caused the glass to move, but Ms. Holder pulled it fast enough to were it stayed still. The inertia allowed the glass to keep its place.

When your daughter pulled it she didn’t use enough force & speed so the cloth didn’t move and the cup was still there but when you applied more force and speed it moved from under the cup because in his first law of motion it states that when an object is at rest it stays at rest and if in motion stays at motion until force is applied (or acted upon) .

Madison, you are correct Amelia would have had an epic fail...I should have just allowed it to happen and made her clean it up. That might have gotten a few chuckles, however, I stopped it because I did not want a mess. She did not have enough force and the lack of inertia would have caused the water to spill. The key word is inertia with the first law of motion. You did a great job with the post. Thank you!

Amelia wasn't able to remove the cloth without moving the glass of water due to her not applying enough motion and external unbalanced force when pulling off the table cloth. Meanwhile, Ms. Holder was able to apply enough force and motion to remove the cloth and not carry the glass of water.

Newtons First law of Motion states "An object in Motion will stay in motion and an object at rest will stay at rest unless acted upon an unbalanced force." This law is one of the main reasons when Amelia pulled the tablecloth the glass moved with it instead of it staying in place because she pulled the tablecloth too slow. When you pulled it the friction between the tablecloth and the table was a lot smaller and caused the glass to stay in place when the tablecloth was pulled. Versus when Amelia pulled it the friction was a lot bigger which caused the glass to move. The inertia also helped play a huge role of why the glass did not move when you pulled it.

When Amelia pulled the cloth from under the cup, she didn't apply enough force quickly enough to stop the water from spilling. However, when Mrs. Holder pulled the cloth, the water didn't spill because just like when Amelia pulled the sheet of paper and the coin went into the cup, Mrs. Holder stopped the water from spilling because she applied enough force quickly.

In Newton's first law the object that is at rest is the glass cup with water where it will stay at rest, while the sheet is in motion with the same speed with a balanced force when Mrs. Holder pulled the sheet. While when Amelia pulled the sheet she had created and unbalanced force then would have gotten her cover in water since it would have caused the glass cup of water to come off with the sheet.

Since, Amelia didn't pull the tablecloth fast enough causing her to almost get wet, but on the other Mrs. Holder pulled it fast enough for the cup to stay in the same place. As newton's first law of motion says that when and an object stays at, it will stay at rest so the object didn't fell the movement of the tablecloth.

The glass cup applied to Newton's 1st law because it was at rest until Amelia tried to pull the table cloth. Which wasn't quick enough and created an unbalanced force, almost causing the cup to fall. On the other hand when Mrs.Holder pulled the table cloth it was fast enough this time. Creating a balanced force and resulting in the cup staying on the table.

When the object is at rest then pulled at the speed that amelia pulled the table cloth it causes a unbalanced force which in this case almost caused the cup to spill on amelia. But in the case of Mrs.Holder it was pulled at a fast enough speed to where it caused a balanced force which caused the cup to not spill on Mrs.Holder.

I think she would've gotten wet (edit, turns out I was right). I thought so because if it's not pulled with enough force at a constant speed, the glass would be dragged along with the cloth. it was an unbalanced force. Mrs Holder was able to take the cloth without tipping the glass because she pulled it quickly, with enough force, and at a constant speed. This applies to Newton's first law since it demonstrates how a still object will stay still unless acted on and by an unbalanced force. Mrs Holder's try at the experiment was a balanced force, so the glass stayed.

She gon get wet cause she pulls it too slow. U gon be dry. When Amelia pulled the cloth, she was hesitant therefore she used little force which resulted in little speed causing an unbalanced force to pull the cup. When Mrs. Holder pulled the cloth, she had confidence pulling it with hella force and speed making the force balanced so the cup had nothing to force it into motion,
