When the paper swiped out from under it quickly the friction doesn’t have enough chance to pull it along Instead the coin at rest there’s nowhere to go but
straight down with the force the gravity
.
What happened to the coin as you pulled the paper?
When you move the paper slowly the coin remains on it but when you move it really fast the coin drops into the glass
. I asked my teacher why is that and he said that it is because of Newton’s First Law, but the law talks about objects with no forces acting on them and in this case force does act on the coin.
What happened to the coin when the cardboard was pulled out quickly?
When the cardboard was thumped, it moved out from under the coin, but because of inertia, the coin had a tendency to remain at rest instead of moving forward with the cardboard. Since the coin did not move forward,
it dropped into the glass
when the cardboard was removed from underneath it..
What happens when you flicked the coin?
When you flick the coin,
it hits the first one (the action) and that coin then tries to move away from the first one (the reaction)
. But it can’t move because it is prevented from doing so by the next coin in the line. So, the force of the impact is passed on to the next coin until it gets to the end of the line.
What happened to the quarter when the card slid out from underneath it?
Explain to students that the
quarter dropped into the cup
when the card slid out from underneath it. This is because the quarter has inertia. The index card was set in motion, but the quarter was at rest. Since there was no force acting on the quarter, it stayed at rest and dropped into the cup.
What happens to the Matchbox case as you pull the cardboard abruptly to the side?
What happens to the Matchbox case as you pulled the cardboard abruptly to the side? Answer.
It makes fire
. Explanation: When you pull anything in the side of the matchbox it causes fire because of friction.
What is the force that causes the coin to fall into the glass?
Gravity
and inertia combine to neatly drop a penny (or a stack of pennies) into a glass.
What will happens when you slowly pulled the cardboard?
Answer: When I slowly pulled the cardboard,
the coin placed on top of the cardboard remained at rest but was dragged along with cardboard
. Explanation: That is because, the coin was dragged by the force in the surface of the cardboard called friction.
How many coins can you add without causing the water to overflow?
How many coins can we add to the water without the glass overflowing?
Gently add coins one by one
. Because of surface tension, the water will rise above the rim of the glass before it spills (just like the initial experiment).
What force pulled the water out of the hole?
First off, when you just held the cup and let your finger off the hole, the water was pulled down by
gravity
and thus water pressure pushes it out the hole.
What happens when you hit the coin at the bottom quickly Why is this so?
Explanation: The coin has inertia, meaning it really wants to stay in one place. If you move the card slowly, it isn’t fast enough to overcome that force. If you flick it quickly,
the coin stays in one place and then drops into the cup
.
When the card is flicked what happens to the coin and why?
A flick is given to the card with finger,
the card flies away and the coin falls in the tumbler
. It is explained by saying that due to inertia, the coin remained at its own place and the card went away due to the flick. While the experiment itself is beautiful, the explanation has loopholes.
Why did the coin rolling on the floor slow down and eventually stop?
Without friction or vibration, the coin (or disc) would spin forever. … The general consensus is that
rolling friction is the main force slowing these objects down
, and ultimately makes them stop.
What keeps an object at rest and what keeps it moving?
Inertia
is the tendency of an object to resist a change in its motion. Because of inertia, a resting object will remain at rest, and a moving object will keep moving. Objects with greater mass have greater inertia. To change the motion of an object, inertia must be overcome by an unbalanced force acting on the object.
Is friction present between a glass of water and the table?
The
glass of water
has inertia — it will not move unless a big enough force acts on it. The force in this activity pulling on the glass of water is the friction between the tablecloth and the glass.
What happens to the 5 pesos Stack coins when you hit the coin at the bottom Why is this so?
what happens to the 5 pesos stack coins when you hit the coin at the bottom? … If you quickly hit the coin at the bottom,
the other coins above the one you hit will remain almost at their places because
according to Newton’s first law, all bodies want to keep their state of rest or uniform motion along a straight line.
