I think the reason that my problems have arisen is because of my equation for the force of friction. I have
Ff= ucosAngle
That right?
Ff= ucosAngle
That right?
I love my equation. What is the angle for a plane surface? 0? Then what is cos0? 1? Then what is 1.mu mg? mu mg? Are the two eqs the same?Originally posted by himanshu121
For eg moving on a plane surface Chroots Ans is correct and in case if body is on inclined surface Kishtiks Ans is correct

It is the limiting force of friction or say max friction force exerted and f force due to friction depends on the circumstance

The force of friction equation is an equation used to calculate the force of friction between two surfaces in contact. It is represented as F = μN, where F is the force of friction, μ is the coefficient of friction, and N is the normal force.
The force of friction is affected by the coefficient of friction, the normal force, and the nature of the surfaces in contact. Other factors that can affect the force of friction include the roughness of the surfaces, the presence of lubricants, and the speed of movement.
The coefficient of friction can be calculated by dividing the force of friction by the normal force. It can also be determined experimentally by measuring the force of friction for different values of the normal force and plotting a graph.
The units of the force of friction depend on the units used for the coefficient of friction and the normal force. If the coefficient of friction is given in decimal form, then the force of friction will have the same units as the normal force. If the coefficient of friction is given in percentage form, then the force of friction will have the same units as the normal force multiplied by 100.
The force of friction acts in the opposite direction to the motion of an object, which can slow down or stop the object's movement. It can also cause an object to change direction or rotate. The force of friction is an important factor in determining the speed and direction of an object's motion.
