Stays putstatic friction 9.80 Nnet force 0.00 N
μk can never exceed μs: lowering the static slider drags the kinetic one down with it.
| Quantity | Value |
|---|---|
| Weight mg | 19.60 N |
| mg sin(θ), along the slope | 9.80 N |
| mg cos(θ), into the slope | 16.97 N |
| Normal force N | 16.97 N |
| Static maximum μsN | 10.18 N |
| Friction force f (static, up the slope) | 9.80 N |
| Acceleration a | 0.00 m/s² |
The block slides only when mg sin(θ) beats the static maximum μsmg cos(θ). At the defaults, 9.80 N pulls down the slope and friction can hold up to 10.18 N, so it stays put. Tip the ramp one more degree and watch the verdict flip.
