The equation for hydrodynamic drag force: drag force equals to fluid density Times Square speed of object times cross sectional area times drag coefficient and divided by two. The drag coefficient is usually dimensionless and the speed of object here refers to the speed of object in relation to the fluid.
Equation: Ff=μFn
Ff= force of friction
Fn= normal force (mass x 9.81 m/s2)
μ= "mu" which is the coefficient of friction, it is unitless
Apply this, Fd = Cdρu2A/2
Where Fd = drag force , Cd = drag co-efficient , ρ = mass density, u = characteristic speed and A = area ;-)

Thrust or friction
F = Ma but the acceleration will be in the opposite direction to that of the object's on which friction force is experienced.
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
I'm afraid you're going to have to be a bit more specific. There are many equations for the various types of friction.

An important formula is that friction = (coefficient of friction) x (normal force).

The force of friction. (FF) An equation relating friction force and the normal force (FN) is.. (FF)=(u)(FN) (u) is the coefficient of friction and it does not have units. It is symbolized by the greek letter mu.

The equation for friction is F=uN. F (friction), u (coefficient of friction), and N (normal). So you first need to solve for the normal by using Newton's second law. Also solve for the x component of the gravity force. Since it is static friction, you know it should be at rest, so that x component force should be the same as the force of friction. Knowing that and the normal, plug it into the equation and solve for u.
Fs=mu*FNFs=Static Friction mu=coefficient of static friction FN=Normal force
Because friction causes a dissipation of heat energy and other kinetic energy. If you use the equation f = ma (Newton's law), where f= force, m= mass; a= acceleration, you can apply this to any machine and factor friction into the mass x acceleration equation. it will always decrease hypothetical force when applied with friction.
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
