Static friction force? mew? do what now? - Physics Forums
2004年12月8日 · How is static friction force different from kinetic friction force? Static friction force acts on stationary objects, while kinetic friction force acts on objects in motion. Static friction force is generally greater than kinetic friction force, as it takes more force to start an object moving than to keep it moving.
Capstan Equation, Friction and Normal Force - Physics Forums
2023年10月7日 · Friction is a crucial factor in the Capstan Equation as it determines the effectiveness of the rope in transmitting force around the capstan. The coefficient of friction (μ) between the rope and the capstan dictates how much the tension can be amplified from one side of the capstan to the other.
Force of friction between wheel and axle - Physics Forums
2009年10月26日 · The force of friction between a wheel and axle can be calculated using the formula F = μN, where F is the force of friction, μ is the coefficient of friction, and N is the normal force between the two surfaces. The coefficient of friction is a measure of how easily the two surfaces slide against each other. What factors affect the force of ...
How to determine the force of friction from a graph? - Physics …
2012年9月29日 · The force of friction is directly proportional to the mass of an object. This means that as the mass of an object increases, the force of friction also increases. How do you calculate the force of friction from a graph? The force of friction can be calculated by multiplying the mass of the object by the slope of the graph.
Minimum Force to Make an Object Move - Physics Forums
2010年9月19日 · In summary, to determine the minimum force necessary to make a 6 kg object slide on a horizontal surface with a coefficient of friction of 0.8, one can use the equation Fsmax = u * Fn, where Fsmax is the force that must be overcome to make an object move, u is the coefficient of friction, and Fn is the normal force.
Calculating Friction in Pin Joints for Linkages | Homework Help
2009年4月19日 · I know the equation for frictional force is F="mu"*N, where "mu" is either the coefficient of static or kinetic friction depending on if the surface is in motion, but I'm not sure how to apply that to a pin joint. The Attempt at a Solution Im assuming the pin to be "loose fitting" so that friction will be basically limited to a point on the ...
Deriving Friction Force: uN | F=uN - Physics Forums
2005年1月9日 · In summary, friction force is the resistance to motion between two surfaces in contact. The formula for deriving friction force is F=uN, where F is the friction force, u is the coefficient of friction, and N is the normal force. The coefficient of friction is a dimensionless constant dependent on material type and surface roughness.
Finding the force of kinetic friction without a coefficient
2016年12月18日 · The force of kinetic friction can be calculated by multiplying the normal force (the force perpendicular to the surface) by the coefficient of kinetic friction. However, if the coefficient is unknown, you can use the formula F k = μ k * N , where F k is the force of kinetic friction, μ k is the coefficient of kinetic friction, and N is the ...
Solving for distance using only initial velocity and coefficient of ...
2008年11月24日 · The conversation also includes attempts at a solution using equations such as force equals mass times acceleration and friction equals the coefficient of friction times the normal force. However, it is ultimately determined that conservation of energy and the equation for kinetic energy can be used to solve the problem.
How do i find the friction force without μ or acceleration?
2019年4月13日 · The friction force can be calculated by using the formula F = μN, where F is the friction force, μ is the coefficient of friction, and N is the normal force. If the coefficient of friction is not known, you can still calculate the friction force by using an estimate for the coefficient of friction or by using experimental data.
