A resistive force
Dimensionless quantity
Static friction μs\mu_sμs
Ffriction=μNF_{\text{friction}} = \mu NFfriction=μN
μ=FfrictionN\mu = \frac{F_{\text{friction}}}{N}μ=NFfriction
N=mgcosθN = mg \cos \thetaN=mgcosθ
F−μmg=maF - \mu mg = maF−μmg=ma
a=g(sinθ−μcosθ)a = g (\sin \theta - \mu \cos \theta)a=g(sinθ−μcosθ)
