If a Normal Force (Fn) is equal and opposite to gravity then why do objects fall?
They fall because the "Fn" is not present until the object is resting on the Earth's surface. Air can not transmit this force.
What is the force that opposes motion between surfaces in relative motion?
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.
When forces are of equal size and opposites direction what is it?
The normal force (Fn).
How do you calculate net force is acting on the mass along the incline?
Just add up all the forces, which in this case is: Ft = Fg + Fn + FD + Ff where Ft is the total force, Fg is the force due to gravity, Fn is the normal force, FD is the drag force, and Ff is the friction force Fg = m*g, where m is the mass and g is acceleration due to gravity. Fn = -m*g*cos(θ), where θ is the angle of the incline from the horizontal. FD = -6*PI*η*r*v, where η is the viscosity, r is the Stoke's radius, and v is the velocity of the mass. Ff = -μ*Fn, where μ is the coefficient of friction.
What is the force applied up or down an object?
Vertical Force? Perhaps abbreviated Fv. If the plane on which it rests is horizontal, then it would be the Normal Force abbreviated Fn.
The overall force acting on an object after all the forces are combined is the?
After all forces are summed with vector addition, the result is usually known as the net force (Fn) and can be used in the formula (Fn = ma).
What does fn in colt serial number stand for?
Part of the serial number. No real meaning.
What is the discrete equation for a Fibonacci number?
Fn = Fn-1 + Fn-2
What happens to the force between two charges if the distance between them is quadrupled?
The new force between the two objects will be 1/16 of what the original force was.This relationship can be found by using this equation:F=(kQ1Q2)/r2In this case "r" represents the distance between the two charges, the "Q"s represent the two charges, the "k" represents Coulomb's constant, and "F" is the force.Since "r" increased by a factor of 4 in the problem, and (4r)2 equals 16r2, then the "new" Force (Fn) is proportional to 1/16r2. You can use proportionality to set up the equation 16Fn = Fo where Fn is the new force and Fo is the original force. If you divide both sides by 16 to solve for Fn, you come up with the fact that the "new" force equals the original force over 16, which demonstrates that the "new" force is 1/16 of the original.

How can you calculate?
One formula that is frequently used is: friction = mu x Fn, where mu (the Greek letter mu) is the coefficient of friction, and Fn is the normal force - the force that pushes the surfaces together, perpendicular to the surface. The coefficient of friction depends on the combination of materials; you can look it up in tables for different combinations of materials; or you can determine it experimentally.
