WebDec 28, 2024 · First we draw the free-body diagram. The force of gravity pointing straight down, and the normal force pointing perpendicular to the surface are the only forces acting. The net force equations are: F_ {netx}=F_g\sin {\theta}=ma\\ F_ {nety}=F_N-F_g\cos (\theta)=0 F netx = F g sinθ = ma F nety = F N − F g cos(θ) = 0 WebOct 1, 2016 · Apply force on the block in horizontal direction till the block just starts to move. This force would be F = μ s M g Once the block starts moving kinetic friction will act on the block. Since coefficient of kinetic friction is numerically less than that of static there will be unbalancing of forces thus causing an acceleration, say a .
