Under the action of constant force F, the object with mass m moves in a straight line with uniform acceleration along the horizontal plane, and the angle between F and the horizontal plane is θ Under the action of constant force F, the object with mass m moves along the horizontal plane with uniform acceleration. The angle between F and the horizontal plane is θ, and the dynamic friction coefficient between the object and the horizontal plane is μ
The resultant force is the component of the pulling force in the horizontal direction minus the friction force, which is equal to μ n:
List: fplane = fcos θ
F = fsin θ
The friction force is: F = μ n = μ (mg fsin θ)
F = f flat - F = fcos θ - μ (mg fsin θ)
=F(cosθ+μsinθ)-μmg
