求动摩擦因数的公式(Formula for calculating frictional coefficient).doc,求动摩擦因数的公式(Formula for calculating frictional coefficient) Several measuring methods of friction coefficient In the high school physics experiment, the method of measuring
Mathematically, μ = F/L. Because both friction and load are calculated in units of force (such as pounds or newtons), the coefficient of friction is dimensionless. The value of the coefficient of friction for a case of one or more bricks sliding on a clean wooden table is about 0.5, w...
Compared with the previous calculating formula for the sliding friction coefficient,the currently inferred one has a relatively small calculating error.This error increases with the increase of the rim angle between the ring and block specimens.Subsequently the reliability and comparability of the ...
Provide the formula for calculating the acceleration of a motor given the moment of inertia and the accelerating torque. Provide the name of the terms in the formula. What is the mass of the object whose acceleration is in the graph? Calculate the force required to change the velocity...
In summary, the formula for friction is F_{friction}=N\mu where N is the normal force and \mu is the coefficient of friction. Normal force is the force exerted on an object from the surface in contact, while coefficient of friction is the constant that defines the slickness between two...
The friction force is best defined using an equation. The force of friction depends on the friction coefficient for the type of friction under consideration and the magnitude of the normal force that the surface exerts on the object. For sliding friction, the frictional force is given by: ...
