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?
The force due to friction: [tex]F = \mu N = \mu m g[/tex] Where [itex]\mu[/itex] is the coefficient of friction (either static of kinetic), and [itex]N[/itex] is the normal force. On a horizontal plane, the normal force is just the weight of the object, which is [itex]mg[/itex]. - Warren
It is the limiting force of friction or say max friction force exerted and f force due to friction depends on the circumstance For eg moving on a plane surface Chroots Ans is correct and in case if body is on inclined surface Kishtiks Ans is correct
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?
