Write a brief explanation of what happened to the coin before and after you removed the index card in Part 1 in terms of forces and Newton’s laws.

Question

Basically, the experiment was the I had a cup and put a notecard on top of it. I then put a coin on top of that. Then, I pulled the index card away very fast like a magician pulling a cloth off a table

anonymous · Answer

The force of friction between the two surfaces of the coin and the notecard was not greater than the  acceleration of the notecard. Because of newton's law of inertia the coin stayed at rest while the notecard was accelerating.

I am not sure if this is the full correct explanation , but that was what came to mind.

So before the index card was removed the coin was at perfect rest sitting on top of the index car. Is that how I would say what happened to the coin BEFORE?
