While your finger is still pushing the coin, there are four forces acting on the coin: what are they?

1) The applied force of your finger

2) The force of gravity acting on the coin

3) The normal force preventing the coin from going into the table

4) The force of friction opposing the motion of the coin

Is there some kind of diagram? how is your finger pushing the coin, and where? It may be:

1) friction against a surface

2) push from the finger

3) gravity

4) air resistance behind the coin
