Traction is the grip a wheel or a foot has on a surface. Lose traction, gain traction, four-wheel traction.
Once a wheel is sliding it has far less grip than one still rolling, which is the whole reason antilock brakes exist. In medicine, traction is a steady pull applied to a limb. Figuratively, an idea gains traction when it starts to catch on.
