Yes. Friction is the resistance between an object and the surface in which it is. When pushing the coin, an opposite force is pushing it the other way, because the forcce you apply to the coin is greater it moves but that doesn´t mean there is no friction.

How do you clean a coin without damaging it?
IF your coin is a common-date coin, pour some baking powder into a bowl put your coins in it then add some quantity of water.......... after 15 mins your coins will look shiny and newBUT NEVER, EVER DO THIS WITH A VALUABLE COIN!!! Cleaning will affect the surface and accelerate any deterioration that already exists.
When you drop a 5 rupee coin and a 2 rupee coin from 100 metres tall building at the same time which one will reach the earth quicker?
If you neglect air resistance, they'll hit the ground at the same time. This is a classic experiment proving that the force of gravity acts the same way on all objects. On the earth objects fall at an acceleration of 9.8 m/sec/sec, meaning their velocity increases 9.8 m/sec for every second they're falling. The same experiment has been done by people ranging from Galileo to American astronauts on the Moon. In reality, air resistance will have an effect on the speed and acceleration at which objects fall. All objects experience friction / resistance from air molecules, so anything that meets more resistance will fall more slowly. That's why a parachute lets a person fall more slowly than if they just dropped - its large surface area increases air friction. However, for similarly-sized items air resistance can be ignored because it will affect both the same way. A 5 rupee coin is larger than a 2 rupee coin so it may be slowed just a bit more. But if you did the same experiment in a vacuum the 2 coins would reach the ground at the same time.
How long does it take a coin to rust in salt water?
It depends on what metals the coin is made from!
How do you know if your 1941 dime is not a proof?
Proof coins were struck at Philadelphia up till 1964 so if your dime has an S or D mint mark next to the E in ONE, that's one indication it can't be a proof coin.If it doesn't have a mint mark, the only way to be 100% sure it's a proof coin would be if it's still in its original package from the Philadelphia Mint. If you found it in circulation a proof coin might still show its mirror-like surface in spite of being worn. The bad news is that once a proof coin has been damaged by being in change, in most cases it loses any special collector value.
Can you gold plate ancient bronze coins and how clean must the coins be?
Gold plating essentially destroys the coin. While it might be technically possible, it would be destroying the details of your coin, especially if unprofessionally done. Cleaning coins also destroys the coin too.
what happens when you slowly pulled the cardboard?
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.

Is it possible to convert the brass penny back to copper again?
By "the" penny, I'm assuming that you mean a penny that has been treated with zinc and sodium hydroxide, and then heated over a flame. To remove the brass plating, you can create friction on the surface of the coin that wears it away, reverting it back to its original copper color.
You toss a coin into a wishing well full of a liquid denser than the coin. will the coin sink?
no, it will float on the surface
What happens when you hit the coin at the bottom?
Friction is a sticky force that appears when 2 objects rub against each other. If you push or pull slowly friction helps pull or push the tower along with the bottom coin. If you push or pull quickly, the coins still rub, but the friction force doesn't have time to get the stack moving. So the coin shoots out without pulling the tower with it.

What is on the surface of an Italian five-cent coin?
Nothing. There is no such thing as an Italian five cent coin.
When you dive for a coin at the bottom of a swimming pool the coin is not exactly where it appeared to be?
It's not where it appears to be because the sun's rays are reflecting off of the water surface, and the water surface are bending the rays, so it looks like the coin is somewhere else.
Can copper coin float on water?
A coin can float on the water under a couple of circumstances. The most obvious is if it is made of a material lighter than water. And the second is if it is broad enough that it can be laid on the surface (carefully) and in such a way that the surface tension is not broken.
Relief of a coin?
The relief of a coin refers to how high the devices (figures and lettering) stand above the field (flat part of the coin surface).
How many forces are acting on a coin after your finger stops pushing down on it?
3 forces gravity drag lift
