But how would you know beforehand which side the coin would land on before you tossed it?

Your equation does not tell you that.

It doesn't tell you unless you always know how much force is applied.

Since weight is only the amount of pull gravity has on an object which mass weight can substitute for mass.

You forget it landing on its edge. That's a third possibility.

Nice equation, but how are you going to know what the inputs are between the time the person begins the flip and when it's caught?

The answer is, you won't. So there goes your dream of 100% predictable coin tosses.

It's better to just have a double head coin.

If it lands on the edge, it still need to flip to one side. That has to be added to your equation. Because your equation is not complete until the coin shows heads or tail.

If you really want to know how many sides a coin has got. It has more than three sides. The coin has two more sides as well. That it can land on.

Probably just have all the other variables in the equation set out.

Then input force last when you get a reading. And find the answer.
(Like how they do it in sports science they get the force)

By landing on its edge I mean like this...

Heads Tails
_____ _____ Edge l

Sorry about the size.

Give me all input variables you think we need and I'll write a proggy

Coin mass, gravity, air pressure, angle of flip, what side it starts on, pressure of thumb with flip, and which area of the coin is hit with the thumb. Those would all be some variables. Also wind speed and direction.

Let's have a look at (part) of variables here:

Definition: Coin is a 3D object in 3D space devised of 3 edges (sorry don't have proper name for acctual 3D body in english - tube with closed edges
)

Object: Coin with 3 edges is tossed to the air. What are the probabilities to hit either of edge?

Scenario 1: (environment we live in; with gravity): To hit 3rd edge (and for coin to stay there) possibility is as low as 1%. So for the other two possibilities we're left with 99% (49.5~% per head/tail)

Scenario 2: (Vacum or space; no gravity) The coin would spin for a long time but would eventualy stop on one of 3 possible sides and stay there. Possibility 1/3 of any edge to hit.

Yeah ... I should define what's up or down in gravity free environment.

That edge also has two sides. That are a bit smaller then the edge you refer to. The odds for the coin to land on the edge of the edge is larger, because of the size of that side of the coin, and because of rotation(Momentum).

But it is still a possibility is it not?

Your equation is right if you either want heads or tails. If the coin shows heads before you toss it. And you want heads to show when it lands. The coin must flip a even number.
The third side doesn't count since it wasn't a part of the experiment.

When I meant rotations I meant rotating back to heads when it is at heads. So one rotation would be back at heads.

But if it did not complete the rotation it would be at half a rotation.
Meaning tails.

Then then if it completed more than half but not one full rotation it would be at it's edge(but unless it is exactly stable at the edge then it will fall).

You have to count the fall as a rotation.

If a coin rotates half way, Its between two sides. If it lands on the edge and falls down it will complete the rotation, It wont matter what side it falls down on. It will complete a rotation either way?

The fall is the final rotation.

Unless it lands PERFECTLY it will fall and complete a rotation.

Which is why it is so hard to create this effect.

Are we at an agreement?

Who really likes to know anyway ?

When I flip a coin it is to let faith decide.

IMO the only ones that want to know, are the ones that plan to cheat.

But seriously I was just wondering.
