How to solve for static friction
WebHow Can You Solve Kinetic and Static Friction Problems? This lesson is part of our unit on Forces for Physics classes and as a foundation for AP Physics classes. WebYou might need: Calculator A 7.0\, \text {kg} 7.0kg box is at rest on a table. The static friction coefficient \mu_s μs between the box and table is 0.40 0.40, and the kinetic friction coefficient \mu_k μk is 0.10 0.10. Then, a 30\,\text N 30N horizontal force is applied to the box.

WebDec 22, 2024 · If you record the applied force at the precise moment the box starts moving, you can re-arrange the static friction equation to find the appropriate coefficient of friction for wood and stone. If it takes 30 N of force to move the block, then the maximum for F s = 30 N, so: F_s = μ_s F_n F s = μsF n Re-arranges to: WebTo get the pallet started, the driver must push it with a force equal to the maximum static friction. P = fs = µ sN = µ smg P = (0.28) (600 kg) (9.8 m/s2) P = 1646 N Once the pallet starts moving, the coefficient of friction drops from its static value to its kinetic value. fk = µ kN = µ kmg fk = (0.17) (600 kg) (9.8 m/s2) fk = 1000 N
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 .
