Friction
... Two children sitting on a sled at rest in the snow ask you to pull them. You pull on the sled’s rope, which makes an angle of 40° with the horizontal. The children have a combined mass of 45 kg, and the sled has a mass of 5.0 kg. The coefficients of static and kinetic friction are µs=0.20 and µk=0.1 ...

The Universal Electrodynamic Force
... The second term on the right is not zero for finite size particles and induced self-field effects. For these reasons it appears that the covariant form of electrodynamics, based on Maxwell's equations, is technically incorrect being based on significant approximations. It is certainly not as fundame ...
