Here, Fn represents the normal force, which is the perpendicular force exerted by the surface on the object, and μ is the coefficient of friction. This formula is typically used to determine the maximum static friction or kinetic friction. What does Fn represent in the friction formula? In the friction formula, Fn represents the normal force.
2. 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. 3.
In summary, the conversation discusses how to find the coefficient of friction when the force of friction is unknown. The equations and variables involved in the problem are stated, and the process of finding the resultant force and net force is explained. The formula for calculating friction force is also provided.
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.
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.
A higher coefficient of friction means there is more resistance to motion, resulting in a smaller displacement. On the other hand, a lower coefficient of friction will result in a larger displacement. 3. Can displacement be negative when using coefficient of friction, mass, and velocity? Yes, displacement can be negative.
To find the minimum coefficient of friction, we can use the formula Ff = μN, where Ff is the force of friction, μ is the coefficient of friction, and N is the normal force. In this case, the normal force is equal to the force needed to keep the child in the circular path, which we found to be 223.976445 N in part 2.
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.
This means that as the friction force increases, the speed of the object also increases. On the other hand, if the friction force decreases, the speed of the object decreases as well. 3. Can an object with no mass have friction force? Yes, an object with no mass can have friction force. Friction force is caused by the interaction between two ...
For part b), we can use the formula F = ma, where F is the friction force, m is the mass of the crate, and a is the acceleration. Since we know the maximum force of static friction from part a), we can rearrange the formula to solve for a: a = F/m = 6.125 N/35kg = 0.175 m/s^2.
