Gravity is acting on every object, but friction between the two objects is the resisting force causing the coin to slow it's horizontal motion across the table surface.
Well it depends on the coin and the tables material, a table is a bit too broad, either what i know could be friction force between the table and the coin or air resistance force. not sure about gravity force
Sorry not sure
The force that slows down a sliding coin on a table is known as friction. Friction acts in the opposite direction of the coin's motion, converting its kinetic energy into heat and causing it to slow down. Factors like surface texture, the weight of the object, and the materials involved can all affect the amount of friction experienced.
